Looks like it's fixed but let's verify with the latest version of Chrome, to be sure...

Confirmed this on Chrome 69. The CL above (https://codereview.chromium.org/1956833002) added StripLayoutHelper.setAccessibilityDescription [1], but it relies on Tab.isHidden [2] which (this part is a guess) is now always false when the tabstrip is open since the tabs are hidden.

[2] https://cs.chromium.org/chromium/src/chrome/android/java/src/org/chromium/chrome/browser/tab/Tab.java?q=%22public boolean isHidden()%22

Per the CL in #3 and the comment in #17 this is fixed. The foreground tab reads the tab title followed by "selected tab".

We also have an accessibility tab switcher on tablets so users have a simple list presentation of open tabs if they don't want to navigate the tab strip.
