Bug 1641802 Comment 0 Edit History

Note: The actual edited comment in the bug view page will always show the original commenter’s name and original timestamp.

**Note**
* When the user shares his screen and then closes the tab with the screen-sharing web-app, the tab-switch-warning will be displayed (incorrectly), leaving the tab somewhat opened, because the other tab wasn't focused due to the appearance of the tab switch warning.
* This issue does not occur if the screen-sharing app is the last tab of the window; another tab is needed, even if it's an about:newtab.
* This issue also does not occur if the other tab from the window has been previously focused while screen sharing (so the tab-switch-warning doesn't appear).
* The real bad issue here is that the browser is still sharing the screen while the tab is closed! This is really bad from a privacy stand-point.

**Affected versions**
* Nightly v78.0a1
* Beta v77.0 (RC)

**Affected platforms**
* Windows 10
* Ubuntu 18.04.4 LTS
* Mac OS 10.12.6


**Steps to reproduce**
Required prefs:
* Flip privacy.webrtc.allowSilencingNotifications to true
* Flip privacy.webrtc.legacyGlobalIndicator to false
* Flip privacy.webrtc.sharedTabWarning to true
1. Engage in a conference.
2. Have at least one other tab open.
3. Share your screen or your window (It does not matter whether you also share the mic and camera or not).
4. Close the tab with the screen-sharing web-app.

**Expected result**
* The tab gets closed, the tab-switch-warning is not displayed, the screen sharing stops.

**Actual result**
* Notice that the tab disappears from the window bar, but the content of the page is still focused and ongoing, and also, the tab-switch-warning gets displayed on the other tab from the window. Even after clicking the "Proceed to tab" button so the browser focuses on the other tab, the screen sharing is still ongoing.


**Regression range**
* This is a feature issue.

**Additional notes**
* This issue was tested with Zoom.
