Display of child/dependent tickets in search results

When a ticket that has child or dependent tickets is displayed, any
child/dependent tickets that are resolved are shown at struck through.

In search results, if child/dependent tickets are shown, resolved ones are
not struck through.

Has anyone patched RT to strike resolved child/dependent tickets in search
results?

Should I report this as a bug?

We’re using RT4.2.8.

Thanks,
Keith
