- `e.error` can be undefined in some cases which would raise an error
inside this error handler, fixed that.
- The displayed message mentions looking into the console, but in my
case of error from `ResizeObserver` there was nothing there, so add this
logging. I think this logging was once there but got lost during
refactoring.
