Answer 1

The temporary workaround, posted by dgozman, worked for me. Reposting here for convenience:

1. Undock your DevTools.
2. Press Ctrl+Shift+I (or Cmd+Opt+I) to open DevTools for DevTools.
3. In second DevTools, select "inspector-app-iframe(inspector.html)" in context selector at the top of console.
4. Execute this code: delete window.localStorage["standardEmulatedDeviceList"];
5. Reopen DevTools.

Answer 2

I just opened an issue in the tracker to help resolve this problem.

If you can, please comment on that issue with your version of Chrome you are using. You may also star the issue (star icon to the far left of the blue box under the search area) to show the issue is affecting you and get updates.

Thank you!
