1551201 - Panic from invalid clip id during display list flattening

Status: RESOLVED WORKSFORME

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

Description

[Nicolas Silva [:nical]]

Moving these signature from bug 1523589 to separate the invalid writes at funky addresses from the failed hashmap lookups.

Relevant bit of info from the original bug:

Adding another recent signature in nightly - all youtube URLs, and all Win 10.

We are trying to look up a clip Id that isn't in the clip_node_map of the NodeIdToIndexMapper in process_common_properties_with_bounds, for various items kinds (I saw Text and Rectangle while going through some of the reports).
