Steps to reproduce the problem:
Use the attached test extension:

1. Right click an unmuted tab and click "mute site".
2. Notice that a chrome.tabs.onUpdated event is fired in the background.js console log, including the MutedInfo property.
3. Right click the tab and unmute it again.
4. Use the extension popup to mute the tab.
5. Right click that tab and click "[un]mute site".
6. Notice that a chrome.tabs.onUpdated event is not fired anymore.

What is the expected behavior?
The browser should always at least fire some kind of "tab updated" event when the user mutes/unmutes via right click, even if you (the developers) don't want the mute state to change.

What went wrong?
I've developed an extension that mutes/unmutes tabs based on their URL and a black/white list. The user has always been able to override the default list behavior by manually muting/unmuting the tab via the right click. As of recently, that has stopped being possible because tab update events no longer fire on right click after an extension has edited the tab state. My extension has a keyboard shortcut to manually override the list behavior, and chrome://flags/#enable-tab-audio-muting still seems to work as it should, but I would still like users to be able to right click to override as well.

Did this work before? Yes Not sure, but this was a fairly recent regression (a few months maybe?).

Does this work in other browsers? N/A
