Who is this PR for?
Educators within remote meetings
What problem does this PR fix?
If someone is running a meeting remotely (eg, MTSS meeting), they start writing a note but then switch to other tabs or browser windows, and not be able to find the original tab they were working in. In that circumstance, there's currently no indication to them that the tab is about to expire (session timeout is currently 30 minutes).
What does this PR do?
This updates the favicon and document title so that there's a visual indication if this is a background tab.
Screenshot (if adding a client-side feature)
This is on IE11, the UX is similar on other browsers as well.
1. in background tab
2. favicon and document title change
3. clicking in the tab, the timeout message is visible
4. clicking revives the session and reset the favicon and title
