Yeah (it's probably the loading-on-completion thing again).

The root problem is that there is no easy way to share the bindings. I
think those keys should be bound to a function which calls runs a hook,
like focus-in and focus-out events are. Actually, it sort of looks like
dframe is trying to install such a hook; the functions it puts don't do
anything except call `dframe-make-frame-{visible,iconify,delete}-function'.
Anyway, at a minimum, we can't have keybindings being modified by just a
load. Here's a patch which moves the keybinding to dframe-frame-mode
activation instead.

Subject: [PATCH] Don't bind dframe events on load (Bug#29599)
* lisp/dframe.el (dframe-set-special-events): New function, containing
previous top-level key binding code.
(dframe-frame-mode): Use it.
