Outer clothes layer on invisible stray does not render at all like other model parts

The stray's outer clothes layer which the player normally sees is not rendered at all when the stray is invisible, and either the player is in spectator, or the stray is on the same team as the player.

Steps to Reproduce:

1. Spawn a stray

2. Make it invisible

   /effect give @e minecraft:invisibility infinite

3. Change your gamemode to spectator

Observed Behavior:

The stray's outer clothes layer will not be visible at all. Only the skeleton part of the model will be visible translucently, and the bow will be visible at full opacity.

Expected Result:

The stray's clothes would be visible regardless of it's effect status, shared team with the player, or the player's gamemode.

Notes:

This is not reporting MC-226182 or MC-110423. Those issues apply for any gamemode, whereas this is specifically reporting when the invisible entity can be seen translucently.
