Status: VERIFIED FIXED

(Firefox :: Sidebar, defect, P1)

Description

When the tab strip is full (i.e., tabs are at their minimum size and scrolling), the updated tab mute icon design causes the tab label to be hidden, and it also pushes the close button off the edge of the tab.

See screenshot for example.

Set release status flags based on info from the regressing bug 1921060

:kcochrane, since you are the author of the regressor, bug 1921060, could you take a look? Also, could you set the severity field?

This was added as part of sidebar changes, so I'm going to move it that component. If we'd prefer to move it to Tabbed Browser instead though, that also works.
