[BUG] animateContextMenus.uc.js freezes when opening bookmark folders too fast.

[Sneakpeakcss]

Describe the bug
When you open a folder in bookmarks toolbar and quickly switch to a different one, the native firefox auto open function freezes.

To Reproduce
Steps to reproduce the behavior:

1. Create few folders on bookmarks toolbar.
2. Open any of them and then start hovering over the rest.
3. If you did it fast enough then at some point auto open stops with one folder opened.

Expected behavior
animateContextMenus shouldn't freeze auto opening.

Desktop (please complete the following information):

• OS: Win10Pro
• Firefox update channel: Nightly / ESR
• Version: 106.0a1 (Nightly) / 102.2.0 (ESR)
• Build ID: 20220914213649 (Nightly) / 20220818165803 (ESR)

Additional context
Beside those folders i didn't notice any other windows having this problem, also while i mainly use ESR with xiaoxiaoflood's loader the same thing happens on Nightly with fx-autoconfig (as seen on included videos).
