The clusterfuzz page says the regression range is:
  Chromium: 323926:323960
  Blink: f0c2b57a82c769daa02c9349933b59d302ae0dc6:d982612927cfb8e3d18b007439ac08873ac8f2b1

It doesn't include my https://chromium.googlesource.com/chromium/src//+/45632fb469f9738299adf8f0877812138bd6d682 .

I attempt to gestures but I could not. It is hard to reproduce...

Since, InsertLineBreakCommand causes this assertion, hitting Return key should trigger. But, there are gestures after Return.

ClusterFuzz has detected this testcase as flaky and is unable to reproduce it in the original crash revision. Skipping fixed testing check and marking it as potentially fixed.
