Do you have a test case that shows this bug?

The doc of `pos-visible-in-window-p' says:

If POS is visible, return t if PARTIALLY is nil; if PARTIALLY is non-nil,
return value is a list of 2 or 6 elements (X Y [RTOP RBOT ROWH VPOS]),
where X and Y are the pixel coordinates relative to the top left corner
of the window.  The remaining elements are omitted if the character after
POS is fully visible; otherwise, RTOP and RBOT are the number of pixels
off-window at the top and bottom of the row, ROWH is the height of the
display row, and VPOS is the row number (0-based) containing POS.

ROWH should be what you're looking for, otherwise?
