Attachment: Addon(s)? Using Status Bar Panel Causing Message Pane Instability

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/119.0.0.0 Safari/537.36

Steps to reproduce:

I'm observing the same behavior as this other user whereby hyperlinks exceeding 219 characters cause message pane instability.
https://www.reddit.com/r/Thunderbird/comments/15sovr6/message_pane_display_instability/

This is observed with Thunderbird 115.5.1 (and earlier versions) on Windows 10 (19044.3693) when an addon that makes use of the status bar panel (profile switcher 3.1 in this instance).

The behavior is the same with hardware acceleration disabled and no other addons enabled.

The behavior only exists if the status bar feature of an addon (E.G. Profile Switcher) is enabled as follows…

Profile Switcher Options - > Show Profile Name -> show profile name in the bottom status bar panel on the right .

See attached video.

The behavior also only exists with my 4k display set to 225% zoom level in Windows. I couldn't reproduce the problem at 1080 resolution and other zoom levels (150, 200, 250). Resizing the Thunderbird window to half screen or less is able to trigger the problem with hyperlinks with less characters.

The behavior is such that right clicking and accessing the context menu for affected hyperlinks is extremely difficult.

My guess is this isn't a problem specifically with the Profile Switcher add-on but rather the handling of the Mail Window Front End / status bar / message pane and either HiDPI displays / certain resolutions / certain zoom levels.

Looks like the button the add-on adds to the status bar (is that through some api?) causes the status bar text to try to be two lines when the link text is long.
I'll note that the Today pane thing is pushed out of the window also without an add-on, for such long links.

We do not have an API to interact with the status bar, and we will not add one.

@Magnus: Do you think we should ask the add-on developer to fix his code? Or does this look like an issue with our code, which could also happen for things we do with the status bar, and therefore we should try to fix this somehow?

Like, always truncating long urls?

Not sure it would fix it for an add or or not, but yeah there's a core bug here. (Updating the summary.)
