This is related to bug #57665, which was a continuous rendering/tbl/man
interaction problem.
The same problem affects mdoc, but I did not investigate the problem for that
macro package.
So the fix for the man part of #57665 needs to be ported to mdoc.
However:
1. That fix introduced a different problem; ugly, misplaced vertical rules;
see bug #63960. It's a lesser problem because it only affects tables with
vertical rules, not _all_ tables.
2. The fix for that newer bug is pretty crude and I think we want a better
one, which I have in mind and am working on presently.
3. Our mdoc implementation has no special support for tbl tables _at all_. I
would have thought this meant that we didn't render those tables for HTML
output at all, because the `HTML-IMAGE` and `HTML-IMAGE-END` tags were
missing. However, startingly, tables appear just fine. (Albeit as images of
converted PostScript output--see bug #60052.)
4. So maybe our man(7) doesn't need those tags either, and we can simplify
its `TS` and `TE` definitions. Investigate this.
