Let's see if it's possible to remove all of them, or simplify (maybe treat Flash `type` as `text/html` and let the affected sites serve HTML or redirect?).

https://chromestatus.com/metrics/feature/timeline/popularity/4740 now shows about 0.002% for December and January. No hits in "Adoption of the feature on top sites". @RByers > In particular, now that I have a rough idea...

Thanks! I agree. @gregorypappas and I also looked at a few in the "top sites" of https://chromestatus.com/metrics/feature/timeline/popularity/4740 , it looks like there are various education and government sites affected also....

Quick GitHub search to get a sense of how common vimeo/dailymotion embeds are compared to youtube. - https://github.com/search?q=youtube.com%2Fv%2F&type=code 82.7k - https://github.com/search?q=youtube-nocookie.com%2Fv%2F&type=code 1.8k - https://github.com/search?q=vimeo.com%2Fmoogaloop.swf&type=code 7.7k - https://github.com/search?q=dailymotion.com%2Fswf%2F&type=code 1.7k

I think it's worth considering switching to require escaped ampersands. The rules for when it's allowed are non-trivial and it's surprising that `&ted` is OK but `&copy` is not OK,...

Thanks @sideshowbarker . I think unescaped ampersand falls into at least: https://html.spec.whatwg.org/multipage/introduction.html#syntax-errors - Unintuitive error-handling behavior (different parsing in data vs attribute values is unintuitive) - Errors involving fragile syntax...

First, when using width descriptors, which seems to be the case here (assuming you mean `w` instead of `px` in your example), the `src` attribute is not added to the...
