Thank you for your report.

This is a limitation of the current Emacs display engine: it can only
set the frame height to an integral multiple of line size.  You can
make sure that this is what Emacs is doing as follows:

  emacs -Q
  click the "maximize" button
  M-: (set-frame-size (selected-frame) (frame-width) (1+ (frame-height))) RET

You will see that the minibuffer is partially obscured by the task
bar.  So Emacs cannot enlarge the frame even by one more line.

I'm closing the bug report.
