Different padding for selects on Firefox

[enogael]

Hi, maybe there's already an open issue for this, but I couldn't find anything.

This is directly related to this fix #32636 that removes some padding on <select> specifically for Firefox with a negative -moz-padding-start.

But it seems this bug has been addressed in Firefox, and now there isn't enough padding ?

Screenshots from the docs either in 5.2 or 5.3 :

Thanks for looking into it :)

@julien-deramond I think Firefox shipped an update to address their padding issue. Wondering if we should remove that custom override now?
