Automatically applying components based on information from OWNERS files. If this seems incorrect, please apply the Test-Predator-Wrong-Components label.

Checked the minimized case, and found that the test is using
window.internals.shadowRoot() to get shadow root, which cannot happen
on the web.

This is an invalid clusterfuzz test case.

Labels: Needs-Feedback
ClusterFuzz testcase 4975946460561408 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.
