When testing if a specific volume is the same as another, I used this command:

execute if blocks -18 56 9 -15 58 12 -18 56 2 all run say true

At the end you can either choose "all" or "masked". However when using "all", the command that is supposed to be ran in case of a successful test, always appears red. Not even autofill options are shown.

If you correctly type the command, it still works, even when it appears red.

I didn´t encounter the same bug when using "masked".

Not a big issue, but still wanted to share.
