viz_browser tests is failing very frequently on https://ci.chromium.org/buildbot/chromium.win/Win10%20Tests%20x64/

All flakes seem to hit a NOTIMPLEMENTED() in DelegatedFrameHost::SetNeedsBeginFrames.

Please take a look and try to fix the issue quickly as the builder is almost never green.

Example:
