Emilio Cobos Álvarez a90d6aad30 Bug 1827304 - Don't override BuildDisplayList in nsFileControlFrame. r=dholbert
That goes back to the introduction of display lists, but I don't think
it's needed, and in fact it causes correctness issues, since the file
selector button is exposed to the web and the implementation removed
here skips painting things like floats.
