What steps will reproduce the problem?
(1) On a MacBook Air running macOS High Sierra Version 10.13 Beta (17A291) open Chrome.
(2) Use Chrome Extension to access Chrome Desktop Capture. (chrome.desktopCapture.chooseDesktopMedia)
(3) Select a screen or window.
(4) Once screen is shared, click the "Stop Sharing" button on the "Screen Capturing is sharing your screen... [Stop Sharing] [Hide]" status bar.
(5) The "Stop Sharing" bar will still be visible, even though the local screen sharing has stopped.  So you can still see the "Screen Capturing is sharing your screen... [Stop Sharing] [Hide]" status bar.


What is the expected result?
This "Stop Sharing Status Bar" should go away when the "Stop Sharing" button is pressed.

What happens instead?
The "Stop Sharing Status Bar" never goes away, no matter how many times you press "Stop Sharing". The hide button also seems to do nothing.

Please provide any additional information below. Attach a screenshot if
possible.
When using Chrome on a computer that works as intended the "Stop Sharing Status Bar" goes away when you press the "Stop Sharing" button.

I have tried resetting Chrome settings.
I have tried uninstalling Chrome and reinstalling Chrome.

I was able to resolve the issue by wiping the Mac Beta OS High Sierra and installing the macOS Sierra.

I've included an attachment image to indicate what I mean when I say "Stop Sharing Status Bar".
