> I was able to reproduce problem 22637 on Emacs for Windows (XP) master branch with the following code starting from Emacs -Q, evaluating the following code in the scratch buffer, and then pressing the F1 key a couple of times.  The last line will remain below the bottom of the visible window each time the F1 key is pressed.  On Windows, a height of 120 seems to work better for purposes of reproducing the problem, whereas on OSX I was using a height of 140.

Thanks.  This is now fixed on the emacs-25 branch.
