Specification: https://html.spec.whatwg.org/ Multipage: https://html.spec.whatwg.org/multipage/#the-iframe-element Complete: https://html.spec.whatwg.org/#the-iframe-element Referrer: Comment: Nothing ever sets the "mute iframe load" flag to false Posted from: 98.110.194.132 User agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.10; rv:41.0) Gecko/20100101 Firefox/41.0
If a load event on an <iframe> does document.open() on the document inside that iframe, the spec sets the "mute iframe load" flag on that document. That means that close() on the document will never fire the load event on that iframe, ever. Not even if there are lots of open()/close() pairs that come from places other than the iframe's load event. This seems a bit odd to me....
