ender chest tooltip incorrect when having ender chest in inventory + being in the ender chest menu

Issue Description:

I am the modpack author, and I found a bug.
visible tooltip continuety issue.

What happens:

the tooltip on the item enderchest in your inventory does not match the actual enderchest you see thants to being in the ender chest menu

What you expected to happen:

i expected it to automatically update when items are moved into the ender chest. (instead of after you close it)

Steps to reproduce:

1. get 2 ender chests (does not matter which world or gamemode)
2. get some other items into your inventory (one of the ender chests count)
3. place an ender chest, open it.
4. move items into ender chest (or visa versa)
   ...
