Summary
<input> of type=checkbox,radio,file doesn't fire `input` events
Chris Rebert
Reported

Per the following portions of the HTML specification: *
https://html.spec.whatwg.org/multipage/forms.html#checkbox-state-(type=checkbox):event-input-input
*
https://html.spec.whatwg.org/multipage/forms.html#radio-button-state-(type=radio):event-input-input
*
https://html.spec.whatwg.org/multipage/forms.html#file-upload-state-(type=file):event-input-input
when the user changes the checkedness of an <input type="checkbox"> or <input type="radio">, or when a user changes the selected files of an <input type="file">, the browser is supposed to fire an `input` event (
https://developer.mozilla.org/en-US/docs/Web/Events/input
) at that <input> element. Safari/WebKit doesn't currently comply with this, and doesn't fire `input` events in these cases. Steps to reproduce: 1. Open
http://jsbin.com/jojoji/edit?html,output
in Chrome. 2. Check the checkbox. 3. Click one of the two radio buttons. 4. Click "Choose File" and select a file. Expected results: After each of steps 2 thru 4, an alert box with the message "input!" should be displayed (because an `input` event should be fired at the respective <input> element). Actual results: No alert boxes are shown because no `input` events were fired. Other info: Equivalent Chrome bug:

Erm, obviously I meant Safari rather than Chrome in the Steps to Reproduce.

Mass move bugs into the DOM component.

As of Safari 13.1, jsbin.com example works as expected (for all <input> types) and web platform tests do pass.

More specific details on the fixes: Starting with Safari 12.1 the radio inputs and checkbox inputs fire “click”, “input”, and “change” events in order when clicked. See
https://bugs.webkit.org/show_bug.cgi?id=190223
https://trac.webkit.org/changeset/236779/webkit
https://webkit.org/blog/8419/release-notes-for-safari-technology-preview-67/
-> "Fixed radio inputs and checkbox inputs to fire “click”, “input”, and “change” events in order when clicked" Preview 67 was mentioned in the 12.1 blog post here (see bottom):
https://webkit.org/blog/8718/new-webkit-features-in-safari-12-1/
Starting with Safari 13.1 finally the file input fires an input event before the change event:

-> "Changed the file input to fire an input event before the change event" Preview 97 was mentioned in the 13.1 blog post here (see bottom):
