When does it happen? We don't use appearance: none ourselves after all.

I think we effectively are, kind-of… I guess… at least with appearance: none it looks the same, IDK about backwards-compatibility with older versions of Firefox where it might’ve been different..?

In any case, what this is supposed to say is that Firefox has some (empirically, 4px) padding in an "unstyled" (i.e. when the native arrow is removed) that Chrome doesn't have. I don't have any other browsers myself ATM to test / compare. Admitted, given that appearance: none is not literally what’s used here, the comment could be clarified.

I changed the wording a bit now.

I’m not sure about the pros and cons of using the “actual” appearance: none property, I haven’t researched too much what distinguishes this property from those -moz-appearance / -webkit-appearance ones; consequently I kept everything as-is with regards to these properties, just to be safe, e.g. since I haven’t tested other browsers, etc…
