Summary:
Placing/breaking the end portal frame in the corners of the portal ender affects the activation of the portal

Breaking the charged end portal frame in the corner of the portal deactivates the portal, and placing and charging the end portal frame with the eye of ender in the corner of the portal re-activates the portal (while making a portal activation sound).

In this case, the portal must still be intact.

Steps to reproduce:

1. Build an ender portal.
2. Charge it up with the eye of ender.
3. Place and charge the end portal frame in one of the corners of the portal.
4. Break the extra placed end portal frame.
5. Place and charge the end portal frame in one of the corners of the portal.
6. Place another end portal frame in another extra corner and break it without charging.

Observed results:
When adding and charging the end portal frame in the corner of the portal, the next portal is activated, and if the portal was already activated, the activation sound is played.
When the end portal frame in the corner of the portal is destroyed, the portal is deactivated.

Expected results:
Placing, charging and breaking the end portal frame in the corner of the portal will not affect the portal in any way.
