The forum nests each post body inside its own table, so ascending to the
nearest enclosing row stopped within that inner table rather than at the
actual post row. The author and profile columns were never in scope, and
every post silently degraded to the placeholder name and the generated
initial avatar instead of the real ones.
Author lookup additionally keyed on a profile link attribute this forum
does not emit at all, so even a correct row would have yielded nothing.
Both conditions failed quietly, which made the result look like a styling
problem rather than a broken DOM traversal.
