Utility items (third slot) drop into inventory when changing belt

[Snooregain Neverhard]

As the title says, when I change a belt - both the former and the new one provide three utility slots, e.g. a Bullet Strap Belt changed to a Large Waist Pack - the third utility slot's content (a grenade stack, for example) is dropped into the inventory and I have to reequip the grenades after the belt change. Why? This is so tedious and can't be intentional, or can it? Maybe I am overlooking some options' switch?

Thanks for any help! Otherwise I suggest to fix this tedious nuisance after eight years finally.

This is a well-known issue but sadly it seems hard baked into the code so it's unlikely to ever get fixed

Well, as a coder I would estimate this to be no more than 30 minutes of work. Strange it has never been fixed given the nuisance it causes to every single player hundrets of times every playthrough.
