Attached file testcase
In this testcase, the rotated green box should not be visible outside the black border. With webrender enabled, the green box is rendered without clipping.
This happens regardless of the webrendest and blob-images prefs.

I'm unable to dump the YAML for this frame, because wrench panics with "TODO: Handle property bindings in wrench!" before it reaches the relevant frame. So I can't find out whether this is a Gecko bug or a WebRender bug.

This is a bug in webrender. I've managed to get the YAML for that frame by commenting out the panic that I ran into.
