When an armor stand is broken by an arrow in Minecraft Java Edition and the items are sucked up by a hopper the order of those items seems to be consistently from left to right: Boots, Leggins, Chestplate, Helmet, Armor Stand.

This allows for consistent item sorting as displayed in this video: https://www.youtube.com/watch?v=xFFK_NXNMqk

In Minecraft Bedrock however, using the same setup (obviously using a half-slab above the hopper for the armor stand to be placed on due to MCPE-55824) the order of items is NOT consistent - apart from the armor stand landing in the 4th slot - the armor items are in a random order.

It would indeed be pretty helpful to have this consistent order in MCPE as well.
