Looks like my change is not relevant.

hajimehoshi@,altimin@: Can you take a look?

Given that it's also base::internal::WeakReferenceOwner::GetRef and blink::UserMediaClient::Create which are leaking and DocumentLoader appears in all leaks I suggest that it's a loading issue.

Status: WontFix (was: Assigned)
ClusterFuzz testcase 5381083825963008 is flaky and no longer crashes, so closing issue.

If this is incorrect, please add ClusterFuzz-Wrong label and re-open the issue.
