BUG: Variable not defined when awaited and rendered inside a snippet

[kroniapp]

Describe the bug

I’m using the experimental async flag.

When rendering an awaited variable inside a snippet — without explicitly declaring it in the snippet parameters — the console throws the following error:

Uncaught (in promise) ReferenceError: value is not defined

I’m currently on v5.38.3. This was working correctly in v5.38.2.
