Describe the bug
Multiline f-strings strip lines that don't contain variables or relevant syntax. See example.
I would expect the example to produce a file that also contains "def", but it doesn't.

Minimal example

rule test:
    output:
        "test.txt"
    run:
        with open(output[0], "w") as f:
            f.write(f"""abc
                def
                {1+1}
            """)

Output (test.txt) of example

abc
                2
            

Note that the second line (containing "def") is missing.
