How to hide tab preview on hover introduced in FF 131?

Hello,

I've already hided the preview of tab name on hover when they introduced it back then with: /* disable preview of a tab name as you hover over it */ #tabbrowser-tab-tooltip { display: none !important; }

but I can't seem to find the selector to hide this new feature as well, so I was wondering if I could get some help :D

Thanks in advance!
