Hello! I have reproduced the issue on Windows 11 with Firefox 153.0.1 by using Winaero Tweaker to change the font to MS UI Gothic and settings `toolkit.legacyUserProfileCustomizations.stylesheets:true` and adding a chrome folder inside the profile with userChrome.css containing `.tab-text {
  font-family: "MS UI Gothic" !important;
}`. The Wikipedia tab title is a little cut off on the left side of the `W` letter. 

However, I can still see the issue if I open a page that contains the letter 'C', for example https://en.wikipedia.org/wiki/Colorado's_congressional_delegations. I can also see it in the Wikipedia tab when there are 5 tabs open in total, and Wikipedia is in 4th place (see screenshot). Should we open a new issue for this or reopen this one? The issue depends on how many tabs are open, I think. Thank you!
