Uncaught exception if widget doesn't respond to API request #21976
Description
Steps to reproduce
- Add a plain web page as a custom widget (ie. one that doesn't support the widget API)
- Open devtools
- See exception
Outcome
This is particularly irritating while developing since it causes the dev tools window to steal focus every time, and also harder to trace due to #21975
