WKWebView takes AppKit's first responder on a press and gpui's view
never asks for it back, so typed text went to the page for good. The
web view now hands it back through wry's focus_parent on every press
gpui gets and when its page drops. The gallery proves it with a native
key after a press on the page. in_view builds only where it is used,
its test covers a box that straddles the view's top, and the embed's
frame takes the card's bottom corners.
