World Border broken
After create the world, everything good. But after I execute /worldborder command [/execute if entity @a in (somewhere) run worldborder set XX] , this command has been broken, and I cannot break/place block in where I execute the command
For example: I execute the command at the end, and I can not break / place block JUST in the end.I still can use the portal and other command

Please elaborate more. Is there a consistent setup to reproduce this in the general case? (fresh world)
