Prevent fieldsets from being disabled form controls

Fieldset elements themselves aren't actually supposed to be disabled
form controls, they are just supposed to make their descendant field
control elements disabled:
https://html.spec.whatwg.org/multipage/form-control-infrastructure.html#concept-fe-disabled

This was causing a bug where SendMouseEventsDisabledFormControls
prevents click/mouseup/mousedown events from being propagated at or
above disabled fieldset elements.
