Here are the place that fire this event in the HTML spec:
https://html.spec.whatwg.org/#checkbox-state-(type=checkbox)
https://html.spec.whatwg.org/#radio-button-state-(type=radio)
https://html.spec.whatwg.org/#file-upload-state-(type=file)
https://html.spec.whatwg.org/#common-input-element-events
https://html.spec.whatwg.org/#send-select-update-notifications
https://html.spec.whatwg.org/#focus-update-steps

All of those concern <input> or <select> elements.

https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement/change_event also mentions <textarea>. I can't find where this happens in the spec but have filed whatwg/html#8073.

I suggest adding "change_event" entries to <input>, <select> and <textarea>.

Per #16651 (comment) I think maybe it's better to go with a single entry on HTMLElement here.
