1682200 - hit testing fails on OOP iframe contents with desktop zooming

Status: RESOLVED FIXED

(Core :: Panning and Zooming, defect, P2)

Description

[Hiroyuki Ikezoe (:hiro)]

This is possibly another variant of bug 1682197.

STR;

1. Open https://bug1682197.bmoattachments.org/attachment.cgi?id=9192951 with enabling Fission on WebRender
2. Pinch zoom in
3. Click the Button inside the OOP iframe

You will NOT see "type: mousedown" event or some such.

Interestingly, for hit testing the button looks like being positioned as if the iframe content is shifted just like the non WebRender case (bug 1682197).

So, the content is visually placed properly, not placed properly for hit testing on WebRender.

Tracking for Fission M6c milestone because APZ hit testing bugs are important.

I just pushed a patch to fix this issue, but I still need to write automated tests for nested iframe case.
