This bug is not a Fenix MVP blocker, so I'll move it to a later milestone. Makoto says Fennec shows dropdown list, but GV doesn't.

Fenix MVP is going to release with or without this fix, so it's not technically a Fenix MVP blocker. I'll move this bug to a later Fenix milestone. Makoto says Fennec shows dropdown list, but GV doesn't.
