Overlapping CSS rules in Select.style and TextInputBase.style

[mkarajohn]

These style rules in Select.style apply the same visuals as these rules from TextInputBase.style.

Since TextInputBase is a building component of Select the Select.style rule seems to be a leftover. It is also more error prone because it targets a child element on which it applies the rule, while the TextInputBase.style rule targets the element in question directly and is also a better solution since it simply uses the :focus-within selector.

If it's confirmed that both rules are not needed we should go ahead and remove the one from Select

This, along with others, will be resolved in the global states ticket.

I think the above links are no longer valid. Is that true? @mkarajohn
