Diablo 2, bug, mercenary losing auras from items

I heard that the bug below is still present after many years and patching up to 1.13:
- If your merc dies, he loses all aura's from equipment. You can fix this by reequipping the item, but the merc will only retain the aura from the last item you reequipped.
It this is true, what should I do if my Hireling dies and I have 2 aura items?
- Can this bug be repaired by restarting game?
- Can you re-equip 1 item, take it off, kill your merc, re-equip second item, or something like that?
- Can you do something to items, like selling them and re-buing, to re-enable the auras again?
- Can hiring new merc repair this bug?
- Can you make new runewords and give it to merc instead of old ones, so he will have auras again?
- Or maybe something else is true?
Or you cannot possibly regain your both auras and must to make new character after your mercenary dies?
I cannot check it myself now, as I don't have runes for it, but depending on where the truth lies, I will make or make not the runewords. I don't want to waste runes on runewords that my merc won't be able to use after he dies.
I would be really grateful if someone could help me and explained either how this bug works or how to solve the problem when it occurs.

The truth, however, is that players can only have one mercenary at a time.How do you do the mercenary glitch?
Mercenaries in general are known to constantly die until they have decent gear. But yea i would remove the Malice and make him an Insight, Strength or Honor. -Heal your merc by holding shift + 1 2 3 4 to quick heal him with potions on your belt. -Always make sure hes within 1-2 levels of your level.How to make your merc untargetable (Mercenary Glitch) | Diablo 2 Resurrected
