Intent to ship: selectionchange for input/textarea
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. Bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1648944 and https://bugzilla.mozilla.org/show_bug.cgi?id=1309626 Standard: https://github.com/w3c/selection-api/issues/53 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. Other browsers: • 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 ___ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform

Intent to unship: HTML element and the context menu feature
It was removed from the HTML spec in 2017 because of the lack of implementer interest (https://github.com/whatwg/html/pull/2742). There is no other browser that implements this feature. Items to be removed: * `` * The `type` attribute of `` * The `onshow` event handler * The `contextMenu` attribute of HTMLElement It will first be hidden behind the flag `dom.menuitem.enabled` and later will be completely removed.

Intent to unship: cross-context @@hasInstance in IDL interfaces
https://github.com/heycam/webidl/pull/356 removed custom hasInstance behavior in 2017, and the feature has only been shipped by Firefox. Dropping the support means that JavaScript `instanceof` operator will return false when the contexts of the object and the constructor don't match, e.g. the object is from an iframe and the constructor is from the top window. The change will initially be only on Nightly to make sure there won't be any significant breakages, and then will propagate to stable versions.

Intent to ship: AbortSignal.abort()
I intend to implement and ship AbortSignal.abort() on all platforms. This is a shortcut function to create an aborted AbortSignal, similar to Promise.reject().
