These failures could mean that the library update changed something and caused
tests to fail. You'll need to review them yourself and decide where to go from here.

In either event, I have done all I can and you will need to take it from here. If you
don't want to land my patch, you can replicate it locally for editing with
./mach vendor dom/webgpu/tests/cts/moz.yaml

When reviewing, please note that this is external code, which needs a full and
careful inspection - not a rubberstamp.
