There are three bugs with very similar behavior but I'm not yet merging them as dupes because there are slight differences. Please feel free to merge if the root cause is the same. 

STS/ChromeVox reads camera app icons/info when gallery view is covering it - 831896

STS reads collapsed additional buttons contents in Calculator - 831961

STS and ChromeVox read buttons under menu in Text application - 831965

Hi Laura, what is the Text application? What is the Camera application? If these are from the web store, could you please link to where you got them? Or are these ARC++ apps?

I found a "text" app on the chrome webstore that matches what you've got in the video.

It looks like they implemented the sidebar by simply placing one menu on top of the other, using a background color to hide the items in the background.

We kind of need something in Blink / automation that tells us if a view is 100% obscured in order to solve this.

 Issue 831961  has been merged into this issue.

 Issue 831896  has been merged into this issue.

The Text and Calculator applications shipped with my Samus and Lulu Chromebooks, nothing added from the webstore nor ARC++. 


I found an area that appears to be similar on the surface but does NOT show the same behavior. 

CrOS environment is the same as that listed above 
# Enable STS
# Open Files, right click a file, select Get Info
Note that an overlay appears. STS reads the contents of the overlay as expected. 

Here's a video showing the correct behavior: https://drive.google.com/file/d/14YD2PPgXnhIgM1Di338F-BLTR2Ddgw8c/view

Web example:
photos.google.com sidebar menu

Possible solution:
Add a function to do a hit test over a rect, and get a percent visible as response. Then we can have a heuristic to read nodes that are greater than some % visible. (There may be a fuzzy hit test that can be used as an example.)

Hit testing is async but may be the best option available.
