10 more AP are needed to enter stealth when using Vanishing Powder Grenade

I'm not sure whether it's intended, but when using Vanishing Powder Grenade, apart from 10 AP to throw it, you also need 10 more AP to actually enter stealth. This has apparently been reported back in 2020 (https://stygiansoftware.com/forums/index.php?topic=6073.msg31870), but there was no response.

I've never used it, but I guess internally the grenade actually tries to use the player's stealth mode ability, rather than applying stealth directly.

Yeah, but it's not clear whether it was intended. One argument that it was not (or maybe a separate bug) is that if you have 10 <= AP < 20, then after throwing this grenade you can end combat in presence of hostiles even though you are not in stealth mode, but combat is immediately re-initiated after that.
