This would be fine, except even in the simple case it returns the same
mistaken result as my alternative solution in the option 1.

For example, with line-spacing 0.2 I see 48.5 text lines visible in my
maximized window, but (window-screen-lines) evaluates to 46.66(6).

Yep, this seems to be the most accurate approach, although probably the
slowest one. Thanks.

Count the screen lines in order to determine in which direction to
render the completion popup (below or above the current line).

I've linked to the related issue in the initial message.
