[MCPE-184732] Combining 2 items with negative durability results in an invisible item that can cause the game to crash

Steps to reproduce:

Run /give @s golden_leggings 2 16500. This should result in you obtaining 2 pieces of golden armor with negative durability
Combine the 2 pieces of armor in the crafting table
Shift click the resulting item into your leggings slot (on Windows)/Unequip the item from your leggings slot (on Android)

Observed result:
Upon combining the 2 pieces of armor, you receive an invisible piece of armor. Shift clicking/unequipping the item results in a game crash.

Expected result:
You receive a visible piece of armor that does not crash the game.

Original description:
As the name of the post implies, upon combining two negative durability items that are low enough to underflow, (a.k.a if the durability of the combination of items goes below -32768), it will generate an item with an invisible texture that if you right click, the game will proceed to crash as shown here.

I suspect it has to do with negative IDs and how the game handle such items. But I have no clue on why this happens

I cannot reproduce the crash. Does this happen without your resource packs enabled?
Edit: I was able to reproduce the crash by shift clicking the item.
