With Emacs 25.3 under MacOS 10.12, a drag with mouse-1 depressed from
the text area of frame F1 to the text area of frame F2 improperly
generates a drag event whose (posn-window (event-end <event>)) shows
F1 rather than F2.
Note that for a drag between frames, posn-window should return a frame
(according to the Elisp manual but not its own doc string). The bug is
that the event itself records the wrong frame (the depress frame rather
than the release frame).
I have confirmed this with Emacs 25.2 under Windows 7 as well.
