Previously due to "rowheader" role we would read out topic titles twice.
This adjusts it so we apply the heading role only to the topic link.
In turn this makes navigation through topic lists more accurate (h) only
lands you on topic links. It also reduces the amount of duplicate reading
NVDA does.
Before:
Topic title link new topic link support link b481 link 19h link 2 button...
After:
Topic title link
This reduces noise, up and down once you land on a topic link can give you
more context.
