Are you 100% sure that's what happens?  AFAICT `read-buffer-to-switch`
uses the minibuffer in the normal way so when we exit the minibuffer the
selected window should definitely not still be the mini-window.
And if it happens with `read-buffer-to-switch` I can't see any reason
why it wouldn't happen for most/all other uses of the minibuffer.
