[Bug] Animations play when re-rendering tabs with virtual scrolling enabled

[awused]

Abstract

I usually have animations on, but with virtual scrolling the tab elements animate into place when they re-render.

Steps to reproduce

1. Keep animations and virtual scrolling enabled
2. Open a lot of tabs and arrange them into trees
3. Scroll up and down

Expected result

Scrolling up and down should not result in any animations playing, since no tabs are actually changing positions or states.

Actual result

Animations play as tabs translate themselves into position. This is often more apparent when scrolling down as scrolling up is more broken with virtual scrolling.

Environment

• Platform (OS): Linux (Fedora 40, x11)
• Version of Firefox: 126 and earlier
• Version (or revision) of Tree Style Tab: 4.0.15

This is also way more apparent with outOfScreenTabsRenderingPages set to 0 instead of 1.

I've found a bugs which can produce this kind problem (re-applying needless animation effect) and introduced patches to fix it. Could you try the development build?

Testing 4.0.17, it doesn't play the animations on scrolling anymore.
