I don't see a call to window-text-pixel-size.  I see calls to
string-width, which is less accurate.

Not the prompt disappears, the entire text of the buffer disappears
from view.  What is left is the text of the after-string from an
overlay.  That's because the window-start of the mini-window is set at
EOB of the minibuffer.
