ReferenceError while having #each inside a snippet

[MartinMikusat]

Describe the bug

While using #each inside a snippet, trying to pass the snippet as an argument to a function defined inside the component definition throws a "ReferenceError: x is not defined"

Passing it to a function defined inside an onclick handler of a button element still works

Removing the #each loop fixes the issue
