Armor stands shift and fall through blocks

Please fix this in 1.2.10; it bothers me when the armor stand "chairs" in my Realm shift out of place.

This bug has been reported to our internal bug tracker for further testing and a fix. It is scheduled to be fixed in one of the future updates (no specific date can be provided).

Please upvote the ticket so we can get an idea of how many players this is affecting.

Can confirm that this is still happening in 1.4.2 on Windows 10. If I walk too far away from my armor stands inside glass they slide to the side anywhere from half a block to a full block Eastward (every time, same direction). Logging out and back in however puts them back in position. 

Can confirm is still affecting builds in 1.8.1

Still affects 1.11.4

Still an issue.  Windows 10 ver 1.14.60, Creative Mode (No other modes tested.)

Should be added to the post: Armor stands shift towards positive x upon reload, but only once.

Resolving issues that were marked as fixed in the 1.15 and 1.16 Betas, now that 1.16.0 is being released.

This has started happening again in 1.20.30. I leave my single player world and the armor stands have fallen through a slab or a solid block.

As of 1.21.51 armor stands are still sinking through solid ground on both single player worlds and on servers. I had to dig them up in solid stone below my build.
