Brewing stand extends arms and inverts its texture when bottles are placed

The bug

If you place a bottle in the brewing stand, you can notice that the arm texture will be flipped and arm extended half pixel outside with default resource pack. In normal state two brewing stand angled arms are pushed half pixel inside with default resource pack.

How to reproduce

1. Place a brewing stand:

   /setblock ~ ~ ~1 brewing_stand

2. Insert a potion into the first slot of the brewing stand:

   /data modify block ~ ~ ~1 Items append value {Slot:0,id:potion,Count:1}

   → The brewing stand arm is not extended

3. Insert a potion into the second or third slot of the brewing stand:

   /data modify block ~ ~ ~1 Items append value {Slot:1,id:potion,Count:1}

   → The brewing stand arm is extended
