This change causes a "Polymer is already defined." error during unit tests. I am
investigating...

Fixed. It turns out that polymer.html must be at the top. This revealed a follow
up error which i fixed below.

Subtle bug that was caught by a test! hidden attribute was overriden by the
:host ::content .dropdown-item display: flex rule (which made a hidden option
not actually hidden), so I had to move it here.
