Looks like there is an unlabeled button in the People section of this page. There's also a button that speaks "change ellipsis" in that section which isn't helpful. I'm not quite able to tell what those two buttons are, since the highlight is not working properly right now. 

@dbeam, can you take a look at this possibly? If not, David can you tackle this? 

fyi: this UI (the old chrome://settings UI) is basically deprecated and is going to be replaced as soon as we possibly can :)

Hope new UI will have a11y-labels for all controls :). 

Some settings have been labeled, however many still remain unlabeled.

Don't see this. The second tab stop belongs to the checkbox allow proxies for shared networks

All I hear is button with 2 items: 56.0.2895.0

Kevin, when filing bugs like these, please include a lot more detail.

The first tab stop is a search text field
The second lands on a list with each listitem pertaining to a network connection
The third is a checkbox with a proper label "allow proxies for shared networks".

What are you expecting here? What would make a better user experience?

Taking a look at this issue

I looked through the buttons on the top level page and only found one unlabeled toggle button for the accessibility options. Created http://crrev.com/2801753003 to fix that, will close this issue when that lands. Please file other issues if you see unlabeled controls.
