dto. seems to work now as expected.

I think, those examples are easy to make up. Line numbers are great for
file contents and maybe input /or/ output. But as soon as in- and output
are mixed up I find them rather disturbing (imagine e.g. a shell
session). On the other hand removing labels and having that nice
highlighting feature with HTML exported files maybe useful in either
case.
I had a quick look at `org-export-number-lines' and the following seems
to work smoothly ...
