Steps to reproduce the problem:
Just use the latest build of canary on macos.  I haven't done anything besides visiting webpages.

What is the expected behavior?
Tabs should be displayed normally.

What went wrong?
In the attached screen recording, notice how the tab UI randomly goes from showing each tab as expected, then for no apparent reason, the tab bar flickers to a solid grey.

Did this work before? Yes Not sure the version, however, i first experienced this bug yesterday (11/16)
