    Bug 1783415 - Don't use custom styling of select in chrome pages. r=mconley, a=RyanVM
    
    Assume default styles fit well enough. This prevents confusing colors from
    applying, since in the described case we pick the hovered select background,
    but then override the options to use the unhovered background...
    
    With short selects (like the ones that have only two options), that may cause
    the wrong impression. A bit tricky!
    
    This repros for me on win10, for what is worth.
