1727821 - Overflowing right-to-left tab title shifts when hovered

Status: NEW

(Firefox :: Tabbed Browser, defect)

Description

[Jonathan Kew [:jfkthame]]

Testcase: using an en-US build of Firefox, in a new window, go to this URL

Note that the tab title is in Arabic script (right-to-left), and overflows the available width.

Now move the mouse in and out of the tab, and observe the text.

Result: when hovered, the text shifts to the left. When un-hovered, it moves back the right.

Expected: the tab title should not move when the mouse hovers over it.

My sense is that the "correct" position is what we see when the tab is hovered. The default (non-hovered) position is crowded up against the close-tab "x" icon.

I guess that in an RTL-localized Firefox, where the tab-close icon is presumably on the left, etc., this might not be an issue, but have not actually tested it there.
