So running just this test case does not reproduce the issue, atleast on a non-MSAN Linux build. Specifically it fast fails due to an invalid SPIRV format error. This makes me suspect that the issue is actually something with the fuzzing target, i.e. memory being retained/leaked between test cases.

This might be resolved by https://dawn-review.googlesource.com/c/dawn/+/2521. So I will rerun this test case once that CL has rolled into Chromium
