That makes sense.
My intent at this point is to continue to define this in terms of abstract
bindings. However, that doesn't mean we can't define the constraints that
those bindings should work under. If you would like particular constraints
specified, e.g. the width of a <select>, please do raise them.
Given this model, though, I don't think the initial request (having a
UA-level rule for <option> that sets display:block outside the context of
a binding) makes sense.
