I noticed, that when you type a command and let it get completed, the suggestions are not really "logged" in the chat but still take space

I think this is a new bugged feature, so I guess that the suggestion goes away is intended

How to reproduce:
1. Bug:

• Type in the chat some words like "Hi" and press ENTER
• Type "/give @p minecraft:" and press TAB and then ESC
• Now open the chat and scroll up, you will still see the suggestions
• Now type "/g" and press TAB
  The suggestions are away (which is pretty usefuly), but they still took space. You can see that when you open the chat and try to scroll to your "Hi", you won't find and it seems like you just started typing, so only 2 lines are occupied

2. Bug:

• Type in the chat some words like "Hi" and press ENTER
• Type "/give @p minecraft:" and press TAB and then ENTER
• Now open the chat and scroll up, you will still see the suggestions
• Now type "/g" and press TAB
  The suggestions are away, but only after you used the suggestion again, it should rather go away when you press ENTER or when you close the chat with ESC
