Armor stand is glitched (not the same as the follow one)

The items in the armor stand sometimes disappear and sometimes don't, which would be linked to MCPE-39779 but sometimes the items are there, sometimes they aren't. It is also inconsistent with the previous version in which everything on the armor stand was normal, but the armor stand was invis. This was very useful, and it would be nice if only the armor stand was invis as it would be quite impractical to have the items invis too.

The attatchments show how it differs in strange ways between the invis and normal ones

What I expected to happen:
Only the armor stand "frame" would disappear

What actually happened:
All items held and worn by the item stand disappeared except the book

Steps to reproduce:
Place amor stand and give it some stuff (manually, no commands)
Use commands to effect it with invis for any amount of time that allows you to easily observe it
Leave the world while it is invis and rejoin (may not be necessary)
Items you would expect to be "floating" disappear and do not follow you like MCPE-39779
