embed: 'display no plugin' algorithm doesn't fire a load/error event #4024
Description
https://html.spec.whatwg.org/multipage/iframe-embed-object.html#display-no-plugin
The "display no plugin" algorithm makes no mention of firing a load or error event. Current browsers seem to fire load events: the following test document in current Firefox results in a X-Frame-Options error with a URL of https://www.google.com/ and a load event:
<!DOCTYPE html>
<embed src="https://google.com/" onload="console.log('load', this);" onerror="console.log('error', this);" />
The display no plugin algorithm should be specified to fire a load event on the element to match current behavior.
