When pushing an active creaking heart using a piston, it still remains powered, but the creaking doesn't detect it when hit.

Steps to reproduce:

1. Create the mechanism as seen in the attached screenshot. This detects the power state of a creaking heart using a comparator, and uses a piston to move it to another comparator. Note the second comparator doesn't have a top pale oak log.

Observed results:
The creaking heart appears to still be powered, but with no top pale oak log.

Expected results:
The creaking heart should not be powered when pushed with a piston.
