Escaped variables are passed incorrectly to child pipelines
Summary
When passing a variable containing an escaped variable to a child pipeline it is evaluated for a second time incorrectly.
Steps to reproduce
Create a variable in the parent pipeline with an escaped variable inside it:
MY_VAR: echo $$HELLO
Print the variable in the child pipeline which results in echo $
