I was able to reproduce the issue on r256238 with the following command: run-webkit-tests imported/w3c/web-platform-tests/media-source/mediasource-replay.html --iterations 5000 -f --debug --exit-after-n-failures 5 -1 --force

Exiting early after 5 failures. 818 tests run.


813 tests ran as expected, 5 didn't (4182 didn't run):

The same flaky failure (internal timeout) happens on platforms GTK and WPE
