I was able to reproduce the text failure locally on my device running macOS Sequoia x86_64 Debug ToT using the following command:

run-webkit-tests fast/webgpu/nocrash/fuzz-282097.html --iterations=10

I found 2 other similar tests that were failing in the same way:

fast/webgpu/nocrash/fuzz-282086.html
fast/webgpu/nocrash/fuzz-283008.html

HISTORY:
https://results.webkit.org/?suite=layout-tests&suite=layout-tests&suite=layout-tests&test=fast%2Fwebgpu%2Fnocrash%2Ffuzz-282086.html&test=fast%2Fwebgpu%2Fnocrash%2Ffuzz-282097.html&test=fast%2Fwebgpu%2Fnocrash%2Ffuzz-283008.html

I will set expectations accordingly.
