      The bug

      When you right click on a customized command block, you will notice empty text fields and/or "Chain" state of the leftmost button, and also disabled "Done" button.

      What I expect:
      The controls immediately display its values after opening the command block screen or telling you that it is loading.

      What actually happened:
      After opening the interface all controls are in the default state (except for the leftmost button, it is in "Chain") and disabled "Done" button. Then after a while all controls display its values.

      My suggestion is to make the command block screen open when the client received the update packet of the command block block entity, like a chest. Or, tell the user that the command block's data is being loaded.

      How to reproduce

      1. Enter a lag-inducing command into a powered repeating command block, e.g:
        /execute if entity @e[distance=100000]
      2. Close and reopen the command block GUI
        →  The command input field will briefly appear blank
