not faviconized webiste's favicon misplaced

[TaivasJumala]

website that don't have favicon including firefox some about:* pages, their favicon misplaced.

i have done a clean reinstall for testing this.

1. setup a new profile in about:profiles
2. install tree style tab
3. ublock expert options, copy & paste user.css
4. the result was shown as image
5. i have tested file in branch development

LibreWolf/Firefox 122.0
TreeStyleTab 3.9.20
Windows 11

I tried same on openSUSE-Tumbleweed(Linux) on Firefox 121/TST 3.9.19, looks nice.
But once I update them to Firefox 122/TST 3.9.20, it also break the style, cause both of them update today.
I havn't test it yet.

update: i download old 3.9.18 TST from github, the sytle is alson bronken, more likely related to firefox.

update again: i download firefox 119 from firefox ftp, it works well, so the style broken is owing to firefox updates.
