fix(mobile): steady overlay entrance while the keyboard dismisses

Opening a bottom-sheet overlay usually dismisses the keyboard in the same
moment, so the panel's keyboard-inset bottom anchor was transitioning down
underneath the panel's own rise animation — a jerky, offset entrance. The
anchor now snaps to its final position for the duration of the enter
animation and resumes animating afterwards (so an already-open overlay
still lifts smoothly when the keyboard reopens).
