[https://lists.gnu.org/archive/html/groff/2026-10/msg00030.html Bento Borges
Schirmer reported a rendering problem to the _groff_ mailing list.]
Right now the problem is latent, masked by bug #68008.
But when exposed, it is reproducible back to _groff_ 1.22.3.
I'll attach a screenshot of the mess in a comment to this ticket so that it
shows up inline. Bento's document attempts nothing complex or clever.

Find out why we're overprinting text here, and fix the rendering.
