Comment 1 Hercules Hjalmarsson 2022-08-31 16:34:28 PDT

For some reason the rdar link didn't get imported/linked correctly, adding manually:

rdar://99409762

Comment 2 Hercules Hjalmarsson 2022-08-31 16:48:14 PDT

This issue can be reproduced using command:

run-webkit-tests -f --exit-after-n-failures 1 --force --child-processes=5 --ios-simulator --iterations=500 imported/w3c/web-platform-tests/mimesniff/mime-types/charset-parameter.window.html
