I ask because I was considering speeding up the search of a RoLS and other rare items even more, by changing the "Display monster loot" option to a value that never displays the dialog.
AND, I'd do that while employing a sweep-and-reload tactic, so I'd need to very quickly check the inventory before reloading, and be relatively confident that I'm not throwing away a finally-found-RoLS

So, that definitely does seem to be the behavior of the game, at least in the current version, but I'd need to be sure that it always, inevitably is.
(I know that doing that would deprive me of the moment of finally seeing a RoLS in the loot dialog, and knowing what monster's soul to thank
