When a creaking with Infested has its heart destroyed, no silverfish spawn

Steps to reproduce:

1. Set the time to midnight.

2. Summon a large amount of creakings by placing creaking hearts between pale oak logs.

3. Give them the Infested effect.

4. Break the creaking hearts.

5. ❌ No silverfish spawn despite the creakings having the Infested effect. This effect still counts instantly killing mobs as damaging them (tested with husks and /kill), therefore the creaking should also have a chance of spawning silverfish.
