Predator has provided 4 possible suspects

1. [Webauthn] Handle duplicate registrations with InvalidStateError by kpaulhamus@chromium.org
2. Prepare LayoutTest expectations for BigInt by jkummerow@chromium.org
3. Remove Syzygy/SyzyASAN build configuration and related code. by siggi@chromium.org
4. DevTools: Search sidebars for source and network by eostroukhov@chromium.org


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

Suspect CL: https://chromium.googlesource.com/chromium/src/+/75dd4f69952c16ed3c5a987081d9c1e9d3c13927

kenrb@ -- 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.
