Unlikely to be the patch in #2. This is a fuzz stack overflow, so I would suspect it's a won't fix.
Status: WontFix (was: Assigned)
Indeed, stack overflow due to a very deep DOM. Thanks vmpstr.

Labels: Needs-Feedback
ClusterFuzz testcase 5662675503415296 is still reproducing on tip-of-tree build (trunk).

If this testcase was not reproducible locally or unworkable, ignore this notification and we will file another bug soon with hopefully a better and workable testcase.

Otherwise, if this is not intended to be fixed (e.g. this is an intentional crash), please add ClusterFuzz-Ignore label to prevent future bug filing with similar crash stacktrace.
