I am using a non-zero line-spacing value and I don’t observe a
difference in the block cursor size in my normal usage. This is likely
because my normal usage includes ‘global-whitespace-mode’ for most
editing modes, with a display mapping for the newline character. I
have customized the ‘whitespace-space’ face to be very unobtrusive.

‘whitespace-mode’ modifies the display of spaces, tab characters, and
newlines, so you can see the difference where it would not otherwise
be visible. With it enabled, from redisplay’s point of view, the
cursor is never at the end of line — instead, it’s on the glyph
substituted for the newline, so the cursor at the logical end of line
has the same height as within the line.
