Thanks for the addon.
I know you have been working on fixing this issue and released a fix but I still have the issue. I made a short vid that shows how the bug is still happening.

Hope this helps.
And I am using Bartender4 V4.17.3.
I know that 2/10/26 is the 12.01 patch so maybe it is fixed with that but I wanted to take the time to report this.
