1661227 - Clicking to focus an OOP iframe inside an OOP iframe fires focus event in the parent iframe

Status: RESOLVED FIXED

(Core :: DOM: UI Events & Focus Handling, defect)

Description

[Henri Sivonen (:hsivonen)]

Spin-off from bug 1653160:

When a A frames B that frames C such that all three are from different domains, when focus is in A, clicking C fires a focus event in B (plus the events that are supposed to fire) in Fission but not in non-Fission.

Fission shouldn't fire the event. This appears to be due to the PuppetWidget of B getting raised.

I also notice that calling window.focus() in frame C would also result in firing a focus event in frame B.

I also notice that calling window.focus() in frame C would also result in firing a focus event in frame B.

window.focus() case should be fixed after bug 1674702.

Thanks. It looks like this one got fixed, too. I'll update the test accordingly.
