Automatically assigning owner based on suspected regression changelist https://chromium.googlesource.com/chromium/src/+/0fade57cc302b008312a196c44bd172ae2b70eac (Enable Modern Media Controls and fix layout tests).

If this is incorrect, please let us know why and apply the Test-Predator-Wrong-CLs label. If you aren't the correct owner for this issue, please unassign yourself as soon as possible so it can be re-triaged.
Status: WontFix (was: Assigned)
This is from my change, but this is happening because the test uses internals to click an overflow button without ever opening the overflow menu, which can't happen without internals. Closing as WontFix

ClusterFuzz testcase 6607004320399360 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.
