Merge "SELECT popup: Touch input should not be able to select disabled OPTIONs." to M54.

In a case of mouseup, we refer to event.target and mouse-related events
are never dispatched on disabled OPTIONs. In a case of touch, we need
to check disabled state manually because we don't use event.target.
