When a select element changes the change event is not propagated up the DOM. This behaviour is provided by at least Firefox and Opera but i have no idea what the spec says about it.
Created attachment 21537 [details] Test case And here's a simple test case
For completeness, see bug #24516 which also discusses Change Event bubbling.
Sounds like a duplicate to me.
I am not able to reproduce this bug in Safari 15.6 on macOS 12.5 and it shows "PASS" whenever I select any other option from drop-down. It is same across all other browsers (Chrome Canary 106 and Firefox Nightly 105) as well. Since all browsers match each other and it seems to be fixed along the way, I am going to tag this as "RESOLVED CONFIGURATION CHANGED". If you are able to reproduce this bug, please reopen and share updated test case. Thanks!
