Status: RESOLVED FIXED

(Firefox :: Tabbed Browser, defect)

Description

Attachment: firefox-address-bar-bug.png

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:91.0) Gecko/20100101 Firefox/91.0

Steps to reproduce:

Visited a page with the title "#𝑮eneral-chat"

Typed "eneral" to bring up the page in the address bar suggestions

Actual results:

Address bar suggestion is triple height

(Prior to the fix for https://bugzilla.mozilla.org/show_bug.cgi?id=1704404, the tab bar was also triple height. 91.0.1 fixed the tab bar, but not the address bar suggestions.

Expected results:

The address bar should be the same height as other suggestions

You can verify this by opening this ticket and then searching for "1727397" in your address bar suggestions. Since the character in question is in the title of the bug (and therefore the page), this ticket page presents the problem.

Also you can verify on the tab tooltip for this bugzilla ticket that the tooltip is also double height.

Address-bar suggestions are covered by bug 1671525, fixed in Firefox 92.

Tooltips were also mentioned in bug 1719436, which was closed as a duplicate but were not in fact fixed by bug 1671525. So I'm updating the summary of this bug to be specific to tooltips as that's the (main?) remaining issue.

The Bugbug bot thinks this bug should belong to the 'Firefox::Address Bar' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

The address bar is just setting the title attribute on <html:span>s, and I imagine the tab overflow menu is doing the same, so this doesn't need to be in the Address Bar component. I don't know whether this belongs in Layout, DOM, or Widget, but over to Widget: Gtk for further triage.

This seems similar to other bugs that Jonathan has recently fixed.
