[Masayuki Nakano [:masayuki] (he/him)(JST, +0900)]

Hmm, it occurs with slow platforms, but there is no meaningful log because:

• Debug build failure is only in Android, which do not show warnings during the test
• Opt build failures occurs with asan and tsan builds which are slow

So, I'm not sure whether I can reach the root cause.

Attachment: Bug 1839265 - Make the `animationend` event listener do not assume that it's always fired for `<dir>` r=m_kato!

According to MDN, animationend event is never fired if the event target (<dir> in this case)
is removed. If it's slow environment, <dir> element may be removed before the listener receives
the event for it. Therefore, it should not assume that it always comes.
