pschumacher@ -- Thank you very much for the detailed steps, could you please share the screen cast as well for better understanding (Facing trouble in settings part of accessibility). It would help in reproducing the issue in the similar fashion.

I tested with two devices and the issues were present in both:
Device 1: 
Device: Pixel 2 XL
Chrome version: 66.0.3359.82   
OS Version: PPR1.180405.005

Device 2: 
Pixel XL
Chrome Version: 66.0.3359.106
OS Version: OPM2.171019.029

Here are a few videos showing the issues on the Pixel XL on O:

Vid 1: https://drive.google.com/open?id=1Y-TImjgNtZUsqCqCpcW_Tg673AUJt_0f 
Shows Talkback autoscrolling correctly while the feature is enabled. Starting at :48 I turned off autoscrolling but it still scrolls on the Google Home page in Chrome. 

Vid 2: https://drive.google.com/open?id=1xDZNZMptnxBr4-GeiDRGQ86Tb-2i2z6C
Shows TB autoscrolling even when the autoscrolling feature is off on a search results page in Chrome. 

Vid 3: https://drive.google.com/open?id=1Z4fvpCnhOy2hgfHxgJMwzcxfbWE4DAUI
Shows that using Switch Access on Chrome, on the Google homepage, the focus goes off screen. The user can then 'select' whatever is in focus offscreen. In this instance it was the privacy link at the bottom of the page. 

Vid 4: https://drive.google.com/open?id=1vVNP2YRPExjiH2u7HshvCkJkYWJUz1V1
Similar to Vid 2, showing that it is possible to select options that are offscreen which shouldn't happen with switch access. 

Vid 5: https://drive.google.com/open?id=154OoKAxil65PMzikLM4J_nrwIgf-HAMz 
Shows using Switch Access on a search results page in Chrome that switch access continues to navigate beyond the visible page. The user is then allowed to navigate for a long time without knowing where the focus is, then they can click and select content they cannot see. 

Vid 6: https://drive.google.com/open?id=1dMJvzURZcIsKeNtHe7qLoOJPaB7KLVaD 
Shows on a search results page in Chrome, if the user scrolls down and then activates Switch Access, the focus is actually picking up content at the very top of the page, rather than the page they are on. In this video, it picks up the search box. The second example has it picking up the account details box.

Tested on the reported Chrome #66.0.3359.82 and latest Canary #68.0.3400.0 using and observed a bit of different behavior by following the steps below:

Settings Updated:
1. Navigate to Device Settings >> Accessibility >> Switch Access >> Settings
2. Tap on "Assign switches for scanning.
3. Update "Select" with "KEYCODE_VOLUME_UP" and Next with "KEYCODE_VOLUME_DOWN"
4. Now, enable "User Service" of "Switch Access"

and

1. Navigate to Device Settings >> Accessibility >> TalkBack >> Settings
2. Disable or Enable "Automatically scroll lists"
3. Now, enable "TalkBack"

Steps Followed:
1. Launched Chrome
2. Navigate to www.google.com
3. Press volume down key continuously. Till highlight looses its visibility.
4. Press volume up key.
5. Observed that one of the link gets clicked (which is not visible to user) and further action takes place.

Note: The above behavior is seen in both the cases when "Automatically scroll lists" is Enabled or Disabled. Which is also an issue.

pschumacher@ -- I observe the different behavior. Could you please look, which could be because of different accessibility settings.

Also, I have requested for the access for the links provided in above comment were I have no access.

Please refer the below URL for the behavior observed:
go/chrome-androidlogs/833639

As the different behavior of issues are being observed, requesting the Accessibility team to look into this issue as well. And, updated the status to Untriaged as the issue is observed.

Not sure, whether the issue is related to Chrome or system's accessibility behavior. Because, when tried the same on FireFox, selection doesn't go beyond the 'Google' logo. (This behavior's screen cast is also updated in above link).

Thanks!

Hi, 
Are you enabling Switch Access and Talkback at the same time? This'll impact the results and many users only use switch access without Talkback enabled. 

After clarifying with the Switch Access team, the focus shouldn't go off the page, if the focus reaches the last visible point on the page, it should then close. Then, if the use clicks on the navigate/next button (in your example the Vol. Down button) the menu option pops up, and then scrolling begins again at the top of the page. The Switch Access team confirmed that scrolling using only the focus isn't a feature on Switch Access, to scroll the user either uses the menu or clicks then the entire page is in focus to scroll. 

Hi pschumacher@ -- Yes, we have enabled Switch Access and Talkback at the same time. However, if the 'Talkback' is turned off, observations still seems to be the same as in Comment #7 if "Automatically scroll lists" is Disabled or Enabled.

Thanks!

Hi, 
The TalkBack setting 'automatically scroll lists' only impacts Talkback, so this being enabled/disabled won't impact a Switch Access user while TB is off. 

I believe the intended result is that when Switch Access focus box gets to the last item visible on the screen, focus will disappear. Clicking the 'next' switch button starts the process over again with focus at the top of the screen. 

There are two issues here, I think the Switch Access bug (focus going offscreen without scrolling) is more severe, bumping the priority.

Able to reproduce TalkBack bug.
Android Version: 9
Chrome Version: 72.0.3607.0
TalkBack Version: 7.2.0

Steps followed:
1. Enable TalkBack via Accessibility shortcut (press and hold both volume buttons)
2. Show global context menu by swiping down and right
3. Select TalkBack settings
4. Disable "automatically scroll lists"
5. Open Chrome
6. Search Google
7. Swipe right until focus box is off screen

Observed behavior:
Scrolls automatically to show focus box on screen

Expected behavior:
Should not scroll if "automatically scroll lists" is turned off

dmazzoni@ - is this supposed to have the UI>Browser component? It seems like an issue interacting with web contents.

Removing other components
