Currently this semi-matches Safari. Chrome seems to not be generating click events at all in this case, but does generate and bubble mousedown and mouseup, and Firefox isn't bubbling any events.

All of the tests fail in all browsers, is that expected? Isn't the behavior of some browser sensible enough to align on?

jgraham · 2022-03-29T18:16:50Z

@saschanaz might be better to answer that question

jgraham · 2022-03-29T18:41:02Z

But Chrome seems to special case disabled form controls to not get a click event, whereas per the test results, Firefox and Safari don't give any mouse events on those controls. I think there are some further differences between Firefox and Safari, but I've forgotten exactly what they are.

(I'm going to close and reopen to update the results in case browsers changed since the test was written).

foolip · 2022-03-30T07:49:08Z

https://wpt.fyi/results/html/semantics/forms/event-propagate-disabled.html?label=pr_head&max-count=1&pr=32381 is now CRASH in Safari, but still all failing in Chrome and Firefox, so probably the same situation still.

saschanaz · 2022-03-30T07:58:05Z

Chrome seems to not be generating click events at all in this case,

Chrome does bubble clicks, please check whether you enabled Experimental Web Platform features flag as the flag blocks bubbling. Demo:

data:text/html;charset=utf-8,<body onclick="console.log('click')" onmousedown="console.log('mousedown')"><input type="text" disabled>

(See also whatwg/html#2368 (comment))

jgraham · 2022-03-30T08:27:45Z

Yeah, we're running this in Chrome dev with the flag set; it sounds like Chrome release might pass the tests as written? Do you happen to know why the experimental flag is blocking (just) click events in this case?

saschanaz · 2022-03-30T08:36:03Z

I have no idea, they once wanted to align with Firefox perhaps?

html/semantics/forms/event-propagate-disabled.html

foolip · 2022-03-30T14:48:40Z

That "SendMouseEventsDisabledFormControls" feature was added in https://source.chromium.org/chromium/chromium/src/+/af6f27363128a72a89cb581f3073c0e068854308 but was never moved out of experimental.

I've run the test locally with ./wpt run --channel stable chrome html/semantics/forms/event-propagate-disabled.html and all the same tests fail, but instead of getting 2 events (3 expected) there are 0 events fired.

Per https://html.spec.whatwg.org/multipage/form-control-infrastructure.html#enabling-and-disabling-form-controls:-the-disabled-attribute only the "click" event should be dropped, so maybe the per-spec behavior is what Chrome does with "SendMouseEventsDisabledFormControls" enabled is correct, and the test should match that?

jgraham · 2022-03-31T16:33:08Z

Well I've updated it a bit, but I'm still not sure what behaviour we actually want to align on. In particular Chrome is still failing the tests for select elements.

josepharhar · 2022-04-07T20:11:33Z

Thanks for making this test! It looks quite comprehensive with bubbling and child elements. Do you think it would be possible to also test mousemove, pointerdown, pointerup, and pointermove?

josepharhar · 2022-06-28T17:31:54Z

Would it also be possible to look at event.composedPath() in this test? It is likely another compat issue we will need to address

saschanaz · 2022-06-28T23:10:11Z

Added it. For now it just includes all nodes as Blink/WebKit do, only to not complicate things before we know what should be done there. I'll adjust it based on the consensus from the next triage meeting.

saschanaz · 2022-07-05T14:15:45Z

I added some more tests for internal request.

Short report:

Both Firefox and Chrome blocks mousedown/up when disabled during immediate propagation, but does not block click
Both Firefox and Chrome changes focuses to the form elements and but Chrome then removes the focus when it's disabled by event listener.

Haven't tested on Safari yet.

jgraham · 2022-07-06T16:12:42Z

Note that https://wpt.fyi/results/html/semantics/forms?label=pr_head&max-count=1&pr=32381 has the latest results for the PR, including in Safari.

saschanaz · 2022-07-06T16:16:42Z

(The current assertions, especially in the new tests (-immediate and -by-parent) are not exactly the requirements. I'll adjust them as we better understand what should be done, hopefully after the triage. For now they are to show the differences.)

saschanaz · 2022-07-06T17:08:59Z

(I wanted to cover over/out events and then found a separate Gecko bug. I think the behavior is same there anyway, so let's just not complicate this further until it's fixed.)

Filed w3c/pointerevents#454.

Corresponds to the latest consensus and also matches what Chrome shipped behind `--enable-blink-features=SendMouseEventsDisabledFormControls`. Imported the portion of tests that is directly impacted here from #32381.
