nvda does not advertise the page title you loaded when you return to the previous page

[fernando-jose-silva]

Steps to reproduce:

open an email message using the default gmail view.
press alt + left arrow to return to the inbox.

Actual behavior:

the nvda is silent.

Expected behavior:

I would like the nvda to announce that I have returned to the inbox.
I know I've returned, plus a novice user can be confused if the command was done successfully.
I have seen this silence when returning to the previous page in other cases.

@fernando-jose-silva can you still reproduce this in Firefox 72.0.1 and NVDA 2019.3 Beta 1?

This is reproducible as follows:

1. Open Firefox and GMail
2. Open more messages from a conversation
3. Press alt+left arrow and alt+right arrow multiple times
   Actual: NVDA will report the page title only when you reach the main page, but not when switching between messages with alt+right arrow and alt+left arrow. Pressing nvda+t will show you that the window title has changed.
   This is also reproducible in Google Chrome 81.
   cc: @jcsteh for Firefox, @aleventhal maybe you have any solution in mind regarding Google Chrome?

Gmail is a single page application. So, when you go back, you aren't actually loading a new web page; behind the scenes, the page just gets updated. That means NVDA doesn't see this as a new document.

That said, Gmail is doing the right thing here (and browsers are honouring that). It focuses the heading of the message when you go back or forward. The problem is that NVDA ignores this because the heading is at the same position in the document. This would have been fixed by #8869, but was reverted in d19b383 due to problems.
