Comment 22

[Josh Matthews [:jdm]]

The intermittancy here is caused by the same problem as bug 1294705. We're always failing this test by dispatching a load event, but sometimes it doesn't get processed before the test decides it's safe to move on.

Attachment: Allow image loads to short-circuit after selecting a source if the new source URL matches the previous one URL

This implements step 5 of https://html.spec.whatwg.org/multipage/embedded-content.html#reacting-to-environment-changes and fixes a common intermittent test failure.

OrangeFactor doesn't show any new reports since this got merged around. Please request Aurora/Beta approval on this when you feel it's baked sufficiently long.

Allow image loads to short-circuit after selecting a source if the new source URL matches the previous one URL

Approval Request Comment
[Feature/regressing bug #]: Unclear if there was a specific trigger or not.
[User impact if declined]: Unhappy sheriffs.
[Describe test coverage new/current, TreeHerder]: A test stops intermittently passing.
[Risks and why]: Caused one immediate regression (bug 1307185), but none have been found since. Only affects a small edge case for image loading (the same URL multiple times), so the risk is well scoped.
[String/UUID change made/needed]: None

[Loic]

Liz, can we keep an eye on this bug for a possible release 50.x due to its regression bugs? It seems to affect some corporate websites/apps.

Comment 39

[Loic]

NB: the work about fixing the regression is in bug 1317901.

Comment 40

[Liz Henry (:lizzard) (relman/hg->git project)]

Yes, thanks Loic! I commented in bug 1317901. Best to nominate there for uplift to mozilla-release and explain why. Ritu is the release manager for 50 so I gave her the heads up in that bug too.
