Thank you.

I can't reproduce it locally, with afl. Asking ClusterFuzz to Redo Task.

The fuzzer says CSSSelectorList::selector_array_ is leaked. But CSSSelectorList is a part of blink_gc object: StyleRule.

So if we really want to free the selector_array_, we need to invoke blink_gc before exiting the fuzzer. As far as I understand, fuzzer doesn't know anything about gc.

I think, it is ok to suppress this asan error. Or fuzzuer should invoke v8 and blink gc after each test?
