Comment 2

[Ed Lee :Mardak]

bug 1966483 probably should only look for primary click so ignore right click

Comment 4

[Ed Lee :Mardak]

was taking a look at handling only primary button click and maybe it wasn't actually bug 1966483 regressing? artifact bisect suggests it might be bug 1965183 but then bug 1966879 switched to expect fail?

Olli, can you please take a look?

Comment 7

[Olli Pettay [:smaug][[e-mail]]]

(I don't see recent failures)

Comment 8

[Henrik Skupin [:whimboo][⌚️UTC+2]]

The tests in this file were marked as intermittently failing in the wpt metadata and as such are no longer reported as failure. So you would have to remove the ini file.

Comment 9

[Henrik Skupin [:whimboo][⌚️UTC+2]]

So this is an issue on MacOS with the test. Removing the metadata I can constantly reproduce the issue. Running in verify mode causes the test to fail all the time. When I comment out setting the microtasks to level 0 at this location for Marionette the test is starting to pass again.

 0:36.49 INFO | `Activation through right-click mouse event` | FAIL    | `assert_true: mousedown event should result in activation expected true got false` |

Here it fails the consumeTransientActivation call with TypeError: Fullscreen request denied.

Given that it also fails without verify mode it should probably not only be a tier2.

I've as well pushed a try build to see if it is failing permanently as well in CI:
https://treeherder.mozilla.org/jobs?repo=try&revision=c2cb926989cee677a2fda7c38224aede518b47e8

Olli, it would be good if you could take a look please. Thanks.

Comment 10

[Henrik Skupin [:whimboo][⌚️UTC+2]]

Note that it also works when I change the test to actually use a left button click. Then fullscreen is entered. So there might be some negative effect of microtask=0 and clicking the right button.

Comment 11

[Olli Pettay [:smaug][[e-mail]]]

So the test shouldn't have passed ever. full-screen-api.mouse-event-allow-left-button-only defaults to false.
It did pass because microtask handling was broken and the relevant code path run outside event dispatch.

If we want to pass the test, enabling the pref in .ini should work.
But I'm not sure if we want that, since it is not the behavior we ship to users.

I assume you meant to say true, because that's the default for this preference.

If we want to pass the test, enabling the pref in .ini should work.
But I'm not sure if we want that, since it is not the behavior we ship to users.

I would agree so. It might be good to pass the test, but that would mean that a spec discussion is needed and all browser vendors agree to the same behavior - which is unlikely to happen soon.

Note that a wpt downstream sync already updated the expectation:
https://hg-edge.mozilla.org/mozilla-central/diff/f9ad94cff87841302b2261c4605bf885c486f1ac/testing/web-platform/meta/html/user-activation/activation-trigger-mouse-right.html.ini

But we probably should get the multiple status removed for macOS. I can provide a patch for that.

Comment 16

[BugBot [:suhaib / :marco/ :calixte]]

The patch landed in nightly and beta is affected.
:whimboo, is this bug important enough to require an uplift?

• If yes, please nominate the patch for beta approval.
  • See https://wiki.mozilla.org/Release_Management/Requesting_an_Uplift for documentation on how to request an uplift.
• If no, please set status-firefox141 to wontfix.

For more information, please visit BugBot documentation.

Comment 17

[Henrik Skupin [:whimboo][⌚️UTC+2]]

I don't think that we have to uplift given that it is just this test which is affected and we only sync with upstream wpt on mozilla-central, and also no failures can be seen.
