Steps 7-9 of the input type change algorithm

Spec: https://html.spec.whatwg.org/multipage/input.html#input-type-change

In short, this resets the selection to the start of the field when the
type has changed from one which doesn't support the selection API to one
that does.

I couldn't see an existing WPT test covering this.
