should an window.open() about:blank document be controlled by opener's controller? #1163

Open wanderview opened 7 years ago

Over in #612 we decided that about:blank documents in iframes should inherit their controller from the parent. This matches the inheritence of the origin.

I think we also similarly inherit the origin when creating the about:blank document for window.open(). Should that about:blank client also be controlled by the opener's service workers?

Repeated from IRC:

I don't think many developers understand about:blank's relationship to the parent/opener. But I think making iframe about:blank and window.open about:blank behave the same is the best thing.

Agreed. The relationship between the auxilary browsing context and the createor browsing context is defined as the same as that of between the child and the parent. So, I think maintaining consistent behaviors make sense.
