Recipe substitutions break highlighting for the recipe

[TapGhoul]

As the title says. Sample code:

#!/usr/bin/env just --justfile

blah:
    ls
    echo "hi"
    ls

blah-bad:
    ls
    echo {{ "hi" }}
    ls

blah-ok-again:
    ls
    echo "hi"
    ls

Resulting highlighting:

This breaks no matter what is in the recipe - a quoted string is used here, but variables break just the same.
