When the preference BlockReturnOfLostItems is set, it prevents checkin from checking the item in, but it does not prevent prompting to fill a hold with that item.

Steps to reproduce:

1. Set BlockReturnOfLostItems to Block
2. Place a hold that can be filled by a particular item
3. Mark that item as Lost (or Missing, or any other flavor of lost)
3. Attempt to check in that item

Expected results:

Message stating that "Item is lost, cannot be checked in./Cannot check in/NOT CHECKED IN", no message about the hold.

Actual results:

The "Item is lost, cannot be checked in./Cannot check in/NOT CHECKED IN" message displays in the page, but is quickly covered by the popup saying that it can fill a hold. If any of the Confirm buttons (Confirm, Confirm and print slip, Confirm and transfer) is clicked in the hold popup, when the popup closes the message in the page below is removed, leaving no sign that the hold was just filled by an item which is now both being held and also lost.
