1918185 - Ensure that VT snapshots handle ancestor clips correctly

Status: RESOLVED FIXED

(Core :: Graphics: WebRender, task, P3)

Description

This will need to be broken down into multiple tasks once I better understand the problem (both in terms of what the specs mandates and how WebRender handles assigning clip chains to pictures).
The code in WebRender that handles how clip chains in/out/across stacking contexts are applied is a bit cursed so I expect this to be more difficult than it seems.

I think that this actually works with the way clipping is implemented currently, but I am waiting for the ability to test on a larger array of real web-content to confirm that.

This has been generally addressed via multiple chnages in the last few months.
