We recently (~~WT-14813~~) introduced a new policy for the eviction server that avoids queuing pages that have relatively few changes when there isn't much cache pressure.

The check for determining whether there is cache pressure causes pages to be skipped if either the updates or dirty utillization is more than ten percent below the configured upper bound.

That should be changed, so that if either updates or dirty is above the threshold then pages are queued.
