Creaking Spawn Egg Not Given when Middle Mouse Clicked

When clicking on a TETHERED Creaking, it doesn't give the Spawn Egg of the Creaking. An UNTETHERED Creaking does give the spawn egg, however.

Steps to reproduce:
1. Use Winter Drop Experiment

2. Spawn a tethered Creaking with a Creaking Heart and two Pale Logs

3. Wait for the Creaking to spawn and middle mouse click
