This is an issue that can occur with some themes on Linux.
border-top was a problem, which I replaced with box-shadow.

[shibotto]

That's a smart idea, but the -0,01px box-shadow is probably the same as no shadow at all. Setting it to -1px however makes it look just like before on every GTK+ theme I tried:

But of course that doesn't work as well for Firefox own themes and that 1px border-like shadow becomes really an eyesore:

If it's not possible to set it only when using the system theme, then probably your current solution is the best one.

Of course, bolding is only possible in Linux system themes.
Thanks to your feedback.
