The initial screensharing UI landed without any test. We are now polishing this UI with bug 1284877 and bug 1284878, and more importantly we are planning to remove the screensharing whitelist to make the feature available to all websites (bug 1127522). As part of this project I think we need to ensure the UI is well covered by tests.

Attached patch Patch v4Splinter Review
The colors I see on the try push from comment 19 are promising at this point, so I think it's time to request review. Panos, I picked you but feel free to redirect to whoever has cycles.

Before landing I intend to file bugs for the AppConstants.platform checks, to mention the bug numbers in the todo() comments.

"nothing" wouldn't be accurate when |expected| has a non-default value, right?

Nit: removing the listener before further action is the more common pattern to avoid inadvertent reentrancy. Is there a particular reason you want it like this here?
