The Bug:

When using command: /advancement grant @s all, Then using /advancement revoke @s all, The notification does not leave the screen but goes through all of the advancements, even when the have been revoked. This might be a bug and its a bit annoying so I reported it to Mojang. Can this be fixed?

Steps to Reproduce:

1. Give yourself all advancements by running the following command.

   /advancement grant @s everything

2. Revoke all advancements from yourself by using the command provided below.

   /advancement revoke @s everything
   

3. Wait around twenty seconds.
4. Take note of how advancement toasts still continue to appear despite the said advancements being revoked just previously.
