Status: RESOLVED DUPLICATE of bug 1982129

(Firefox :: Sidebar, defect)

Description

Attachment: firefox_ucS9ZAWRvl-ezgif.com-video-to-gif-converter.gif

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:142.0) Gecko/20100101 Firefox/142.0

Steps to reproduce:

Settings I have
sidebar.visibility set to "expand-on-hover"
sidebar.animation.enabled set to "false"

I tested the exact same settings in version 141.0 - same results and 140.0 - works correctly.

"Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:142.0) Gecko/20100101 Firefox/142.0"

Actual results:

If I pass my cursor over the sidebar without stopping, it will expand and stay open. Moving left always leaves it expanded, moving right will only collapse if I move the cursor slowly.
And occasionally, the sidebar will stop expanding at all until I expand it with the toolbar icon.

Expected results:

Sidebar should only expand when I stop my cursor on it for a short time, and then collapse only after I move the cursor away from it.
