Bulk-WontFixing these bugs. This was a bug on ClusterFuzz side, see bug 717534. We will start seeing new testcases auto-filed in a day or two. We can't leave these open as ClusterFuzz won't autoverify them after ClusterFuzz-Wrong label.

We have made a bunch of changes on ClusterFuzz side, so resetting ClusterFuzz-Wrong label.
