Bug 9267 – Quirksmode: Handler for event target is executed during the capture phase

• Component: UI Events
• Status: RESOLVED CONFIGURATION CHANGED

[Adele Peterson]

http://www.quirksmode.org/bugreports/archives/safari/index.html

"The DOM 2 event spec requires that the capture phase event handlers should only be activated on ancestors of the event target, and not the event target itself. Mozilla and Safari break this rule in different ways, and fire it on the event target as well.

Workaround is included
Reported by: TarquinWJ."

Changing component, good testcase.

I'm not sure if it's still valid bug report.

Since Opera 10 mimics Firefox behavior in this test.

Re-categorizing; this looks like an event handling bug.

I am getting following behavior across all browsers based on attached test case:

*** Safari 15.5 on macOS 12.4 ***

-> <div> capture dialog
-> Error dialog [paragraph capture]
-> paragraph bubble dialog
-> <div> bubble dialog

*** Chrome Canary 105 on macOS 12.4 *** (matches with Safari 15.5)

-> <div> capture dialog
-> Error dialog [paragraph capture]
-> paragraph bubble dialog
-> <div> bubble dialog

*** Firefox Nightly on macOS 12.4 ***

-> <div> capture dialog
-> paragraph bubble dialog
-> Error dialog [paragraph capture]
-> <div> bubble dialog

I am not clear on what is expected behavior but since it is raised to match Firefox behavior, which is still not the case. I think it is still reproducible. Thanks!

Firefox Nightly 124 is now behaving same as Safari / WebKit.

So marking this as 'RESOLVED CONFIGURATION CHANGED'.
