Select Dismissal Unexpected Behavior

@martin Hey sorry for the notification, looks like you pushed the commit in question linked above.

Any chance you could check if this seems accurate as the root cause of what we’re seeing? We’re seeing huge filter lists in the queries (~a million topic ids) in the default case of “dismiss all new”. (our forum hosts tons of Discourse topics)

We could help with a PR to resolve it if Discourse team has no priority for this, but I doubt we are the only ones affected by this, might also be impacting DB performance of some of your customers.
