1926293 - Moving tab to existing group in another window breaks both windows

Status: RESOLVED FIXED

(Firefox :: Tabbed Browser, defect, P1)

Description

[Dão Gottwald [:dao]]

When attempting to move a tab to an existing group in another window, the original window ends up with no selected tab and the target window ends up with two selected tabs. I also see these errors in the browser console:

JavaScript error: chrome://browser/content/tabbrowser/tab.js, line 111: TypeError: this.initialize is not a function
JavaScript error: chrome://global/content/elements/text.js, line 99: TypeError: this.delayConnectedCallback is not a function

I would like to verify this fix, but I need steps to reproduce. How exactly does group tabs work? Is it a feature that needs to be enabled? Is it an addon? Can you help me?

QA could not reproduce this window breakage on the affected Nightly v133.0a1 (2024-10-27) on Windows 10, MacOS 11.7.10, MacOS 15.3 and Ubuntu 22. In the lack of clear steps to reproduce, we will assume that the reporter might have a less common environment it reproduces on. In conclusion, we will remove the qe+ tag as we can't verify the fix if we can't reproduce the issue.
Please NI me for further testing if clear steps to reproduce are provided. Thank you!
