Vindicators can drop multiple axes

I was fighting a raid in MCBE and a vindicator dropped two iron axes

What I expected to happen was:

The vindicator would drop a emerald and maybe a iron axe

What actually happened was:

The vindicator dropped two iron axes

Steps to reproduce 

1.  Drink a Bad Omen V potion in a village
2. Kill some vindicators and eventually one of them will drop two iron axes
