Predator and CL could not provide any possible suspects.

Using Code Search for the file, "core/frame/web_local_frame_impl.cc" suspecting the below Cl might have caused this issue

Suspect CL: https://chromium.googlesource.com/chromium/src/+/02a177efe6b2aa5f042064aa981003ee6c2ef996

dcheng@ -- 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!

kenrb, do you mind looking at this one? I don't have an immediate theory on what's going on--we're in the middle of update style, where script should be forbidden, but maybe the frame is detached somehow?
