Drawterm registers the keydown event, this trickles down to
kbdfs, rio, and whatever, modifying their input states;
then, drawterm's input focus is taken away by external
forces, you release the key but drawterm doesn't ever get
that keyup event, therefore everything continues to believe
you are holding down that Ctrl key for life.

I remember trying to work this out at some point, with the
idea of tracking the keys being pressed and explicitly
releasing them on focuslost event, or something like that.

You can't do it wholesale or naively either, because for
example Alt triggers the kbdfs compose mode that must be
exited by pressing Alt again.
