I refer to the following text from

The attached 'window-recenter-region-start-position' should address
that.  I am not aware of whether we have a function on master to get the
line height of a specific window as if a specific buffer were displayed
in it so I used 'frame-char-height' for the window in question.  The
rest of the function is straightforward but there might be off-by-one
glitches.

Roughly tested with the also contained 'recenter-region'.
