SecretScreen built its child alone, and a stack around it with the cover
while the app was away (iOS), so each switch of apps built the child anew:
a phrase field lost its focus, its caret and what the keyboard was
composing (the short reading's L4). It always builds the stack now, laid
out as the child alone (StackFit.passthrough), the cover in it only while
away.
