This was a very confusing part for me. I wasn't sure how I should have passed
these objects down to WebWidget. I can see inside blink we would like to use
Members to keep track of pointers and stuff. But then that structure is not
visible outside. On the other hand, we have ui::ScopedWebInputEvent which is
outside of Blink. So I was not sure what the best way of passing this would be.
Do you have any suggestions?
