[Rares Doghi, Desktop QA]

Im not sure if this is the correct component for this issue, maybe someone from our dev team can take a look and move it to the correct component. Also adding the Qa-Not-Actionable tag for now since there are no steps for us to try and reproduce it.

Rust panic, ultimately from webrender::clip::ClipTreeBuilder::define_clip_chain.
