Summary: selectionchange for text controls has been behind the flag `dom.select_events.textcontrols.enabled`, while the behaviour was different from Chrome’s as the events fired at each element instead of `document`. I intend to modify the behaviour to make the events fire at `document` and thus follow Chrome’s behaviour.
Platform coverage: All
Preference: Enabled by default, but still controlled by `dom.select_events.textcontrols.selectionchange.enabled`. Note that the flag is changed to enable `selectstart` separately in the future.
• Chrome: Shipped
• Safari: Shipped
web-platform-tests: There is no wpt coverage yet.
• Blocked by test_driver not allowing intermediate mouse state https://github.com/web-platform-tests/wpt/issues/24944
Secure contexts: No, as other browsers already shipped this without restriction
Is this feature enabled by default in sandboxed iframes?: Yes
