Description
The composed property determines whether an event that occurs in shadow DOM will bubble to the host element.
In HTML, all form control input events are composed 1 2.
Presently, we are not instantiating input events with { composed: true }. See for example fillIn and select. I have not looked if there are other places. It probably makes sense to make this change in fireEvent itself similar to how bubbles is true by default.
