Predator and CL could not provide any possible suspects.

Using Code Search for the file, "media_control_overflow_menu_list_element.cc" suspecting the below Cl might have caused this issue

Suspect CL: https://chromium.googlesource.com/chromium/src/+/b9efa14b6519436365827fff7444ff66bc935f01%5E%21/third_party/blink/renderer/modules/media_controls/elements/media_control_overflow_menu_list_element.cc

mlamouri@ -- Could you please check whether this is caused with respect to your change, if not please help us in assigning it to the right owner.

Thanks!

Labels: Needs-Feedback
ClusterFuzz testcase 5399712614842368 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.
