The change I made shouldn't affect this call stack at all.

https://chromium.googlesource.com/chromium/src/+/d83b571dc700010f144b68fe3d8628923c008773 based on regression range.  Nasko, feel free to bounce back if I'm wrong.  Thanks

Adding rbpotter@ too, since there are two CLs in the range that include print preview work.

Most of the changes in those CLs are adding browser tests for the new Print Preview UI. The few other changes are to code for the componentized UI that is behind a flag that is turned off by default, and I don't see any indication in the report that cluster fuzz turned it on. I also am not sure how print preview changes would cause that stack trace.

The relevant code in content/shell/test_runner/web_frame_test_client.cc has nothing to do with printing.

I think I have an idea why it might be due to my CL, as I got a different report from ClusterFuzz about hitting a CHECK through test code that I fully understand. I'll poke a this next week, but lowering priority and severity as this is likely just test code.
