The test was added as part of web-platform-tests/preload resync and 260462@main is not the cause of the Assertion, but just when the test was added and uncovered a pre-existing condition. This issue can be bisected to 260462@main using the command: run-webkit-tests --debug -f --clobber-old-results --exit-after-n-failures 1 --force --child-processes=5 --iterations=50 -1
