> If it's easy to implement, we could just try it:

Implement what?  The line-height calculation was just one aspect of
the issue; the other aspects are still not clear: when to avoid
displaying a number, how to display numbers on the line people want it
to be, etc.

If we just implement the height part, all it will do in the use case
that started this thread, for example, will be display a one-pixel
"number" on the screen line that shows the yellow line, and no number
at all on the text line which follows it.  IOW, you will see
line-numbers 1 and 3, and no number 2.  Which is trading one display
glitch for another, right?
