Turns out this is only a problem in the "argus" theme.

And when doing this in the "light" theme this happens:

You cannot read "Open state" anymore

The reason is --fallback-bc or --bc being the same as button-primary.

.. and the reason we have that hover at all is because they are inside a <ul> with class menu. If we remove the menu classes color is ok but lots of whitespace is missing and everything shifts left.

It is easier to remove the menu class and apply some of its styles to relevant tags instead to fix the postioning
