If I have line-spacing set, the value the above function returns is
smaller than the actuall number of screen lines the window can contain.

For example, when I have the current Emacs frame maximized and
line-spacing set to 0.2, (window-screen-lines) returns 46.66(6), whereas
there are 48 fully-visible lines in the given window and one
partially-visible one.

Here's my default font:

  (set-face-attribute 'default nil :height 105 :family "Fira Mono")
