So what I was expecting is to command change when I misspell some part when the command block is in repeat mode and in always active. But later on I open the command block again, the commands in there reset of the first command I type

How to reproduce:
1 Type any command in the command block
2. Turn the command block in repeat mode
3. Turn the command block in always active
4. Close the command block menu
5. Open the command block
6. Change the command you type in the command block
7. Leave the command block menu
8. Open again the command block
9. As you can see, the command block keep resetting to the first command
