[Bug] Autohide expands behind window content

[ned-martin]

Abstract

TST is set to autohide. When mouse hover it should expand over the top of the window, but it is now expanding behind the window content.

Steps to reproduce

1. Upgrade Firefox to 133.0b2 when TST is set to auto-hide and expand on hover. This works on previous versions of Firefox.

Expected result

Actual result

TST auto-hidden

TST with mouse hover - now expanded behind the window content

How it should work

Environment

• Platform (OS): Windows 11
• Version of Firefox: 133.0b2
• Version (or revision) of Tree Style Tab: 4.0.23

Autohide is not a feature of TST, it is a userChrome.css customization topic. Thus I move this from issues to discussions.
