[1.10] Armor stand texture glitched

Partner Rank:

2 (important)

Partner Team Reporting:

Verification builds and Platforms:

1.10.0 Pre-Beta Windows - #1591852

Summary:

When placing an armor stand into world, the texture does not display correctly. (all white)
When placing armor onto the stand, that armor is also does not display correctly (all white)

This does not seem to effect armor icons, or armor that is on the player

Also it seems that the alpha to the HD armor is working, it is just the color information that is lacking.

Impact:

Will effect HD 128x and 64x Resourcepacks on the marketplace right now. (it does not effect vanilla minecraft)

Repro Steps:

1. Download an HD resource pack (ZigZag/Sphax/Chroma Hills)
2. Start a new game in creative and place an armor stand
3. Place armor on the armor stand

Observed Results:

Both the armor stand and the placed armor will be all white. They will respect the alpha of the HD pack but not the diffuse

Expected Results:

Armor and armor stand render in full color

Screenshots/Videos attached: Yes/No

Yes, screenshots attached 

Regression Builds:

Did not occur in 1.8

Notes:

Might have been something new introduced in this early beta that is effecting the way armor is colored. I've tested in Chroma Hills and Sphax to see if it was ZigZag specific, but it is occurring in all 128x packs.
