1743215 - All contents in an inert frame should also be inert

Status: RESOLVED INVALID

(Core :: DOM: Core & HTML, defect)

Description

[Oriol Brufau [:Oriol]]

See https://html.spec.whatwg.org/multipage/interaction.html#inert

While a browsing context container is marked as inert, its nested browsing context's active document, and all nodes in that Document, must be marked as inert.

(A "browsing context container" is something like a <frame> or <iframe>)

WebKit (https://webkit.org/b/233532) and Firefox don't do that. Chromium does.

I plan to add a test in https://chromium-review.googlesource.com/c/chromium/src/+/3302812

A bit weird that that would affect even cross-origin subframes... Seems like you could observe whether the embedder element is inert which is a bit suspect.

Yes, this was bad. I removed it from the spec and from Blink.
