As far as the X server knows, all resolution changes are intended to be
permanent configuration changes, not temporary for the life of a certain
app which just happens to be displaying a window the same size as the
screen resolution.   There's nothing for it to "restore".

To do what you want I believe you'd have to update the RandR extension to
somehow capture intent - perhaps a new request to specify that any
resolution changes requested by this client only be applied when the
client has focus.
