1530239 - css transition events must fire even if an element is disabled

Status: RESOLVED FIXED

(Core :: DOM: Events, enhancement, P1)

Description

[Marcos Caceres [:marcosc]]

Currently transitionstart and transitionend events won't fire if an input element is disabled.

Expected:
they should fire.

Actual:
they don't fire.

Bug 329509 contains a reduced test case.

Note to MDN team: I've added a note to the Fx67 rel notes: https://developer.mozilla.org/en-US/docs/Mozilla/Firefox/Releases/67#DOM_events

not sure what else we need in terms of docs.
