Activate window on swipe-to-reply.

A touchpad swipe-to-reply works on an unfocused window, because scroll
events are delivered to the window under the pointer without moving
keyboard focus. The reply bar opened, but keystrokes kept going to the
previously focused application. Request window activation when a swipe
triggers a reply, like other reply flows already do.
