Unable to Equip Wolf Armor in Realms Worlds created before 1.20.80

Players cannot equip Wolf Armor to their tame wolves on Realms Worlds that were loaded to the Realm Server before the 1.20.80 release.

Steps to Reproduce:
1. Have a pre-existing Realms world
2. Load the World and tame a Wolf or use an already tame Wolf (that you own).
3. Craft and/or have Wolf Armor in Inventory
4. After taming a Wolf, attempt to interact with the Wolf whilst holding the Wolf Armor Item

Observed Results: 
1. The tame Wolf will only sit/stand when being interacted with whilst holding the Wolf Armor Item

Expected Results: 
1. After interacting with a tame wolf whilst holding Wolf Armor, the Wolf should now be equipped with the Armor

Attachments: 
1. Test 1
"Wolf Armor Equip Test" on a Realms World that was active and loaded before the 1.20.80 release
2. Test 2
"Wolf Armor Equip Test" in a Local World that was created before the 1.20.80 release
3. Test 3
"Wolf Armor Equip Test" in a Local World freshly created after the 1.20.80 release
4. Test 4
"Wolf Armor Equip Test" in the same World created in Test 3 (above) but loaded onto a new Realm Server.
5. Test 5
"Wolf Armor Equip Test" on a different Realms World from Test 1, but also a World that was loaded and Active prior to the 1.20.80 release
6. Test 6
"Wolf Armor Equip Test" in the same World as Test 5, but as a Local World downloaded from the Realm Server. 
7. Test 7
"Wolf Armor Equip Test" in the same World as Test 5 & 6, but re-uploaded to the Realm Server. 
8. Download Error
I made an attempt to Download the World from the Realms Server that was used in Test 1 above but encountered an error, so I repeated the Testing in a different World on a Realms Server 

Notes: 
 
Test 1 - Carried out on a Realms Server in a World that was created before the 1.20.80 release. I expected to see the Wolf Armor be successfully equipped to a Tamed Wolf.
Test Failed 

Test 2 - Carried out in a Local World created before the 1.20.80 release. I expected to see the Wolf Armor be successfully equipped to a Tamed Wolf.Test Passed

Test 3 - Carried out in a newly created world after the 1.20.80 release.  I expected to see the Wolf Armor be successfully equipped to a Tamed Wolf.
Test Passed

Test 4 - Carried out in the same world as Test 3, but with the World now loaded onto a Realms Server. I expected to see the Wolf Armor be successfully equipped to a Tamed Wolf.
Test Passed

Test 5 -  Carried out on a Realms Server in a World created before the 1.20.80 release but different from the World used in Test 1. I expected to see the Wolf Armor be successfully equipped to a Tamed Wolf.
Test Failed 

Test 6 - Carried out in the same world as Test 5, but with the World now downloaded as a Local World. I expected to see the Wolf Armor be successfully equipped to a Tamed Wolf.
Test Passed

Test 7 - Carried out in the same world as Test 5 & 6, but with the World now loaded back onto a Realms Server. I expected to see the Wolf Armor be successfully equipped to a Tamed Wolf.
Test Passed

The issue only occurs on Realms Worlds created before the 1.20.80 date. Downloading the World and re-uploading it to the Realm appears to rectify the issue, if only as a jerry-rig option, until the bug has been fixed.
