I am able to reproduce this issue with r259868 and r259850, but I cannot reproduce the issue on r259849 using this command:
run-webkit-tests  --iterations 99 --exit-after-n-failures 3 --force -f --debug -1 media/track/track-user-stylesheet.html

r259850:
[6/99] media/track/track-user-stylesheet.html failed unexpectedly (text diff)
[6/99] media/track/track-user-stylesheet.html failed unexpectedly (text diff)
[6/99] media/track/track-user-stylesheet.html failed unexpectedly (text diff)
Exiting early after 3 failures. 3 tests run.
0 tests ran as expected, 3 didn't (96 didn't run):

r259849:
All 99 tests ran as expected.
