End Portals can generate the portal blocks outside of the portal if the portal frames are incorrectly rotated

The Bug

End portals can generate in invalid locations if the end portal frames are rotated incorrectly.

Steps to Reproduce

  • Build the setup as shown in the attachment below. setup.png

  • Place an eye of ender in the end portal frame that doesn't have one, and as you do this, take note of where the end portal blocks generate.

Observed Behavior

End portals can generate in invalid locations if the end portal frames are rotated incorrectly.

Expected Behavior

End portals would not be able to generate in invalid locations when the end portal frames are rotated incorrectly. Instead, end portal blocks should always be generated within the end portal frames.

Can you provide steps to reproduce this?

the end portal frames are facing the wrong direction in the photo, but it is weird that it ends up having that effect. (to build a correct portal, stand in the center and place the frame blocks all around you)

Even building it with end portals facing the wrong direction, I can't seem to make this happen. This is an easy screenshot to fake, though. So I still think we need instructions how to reproduce this.

Confirmed, reproducible in 2 configurations and likely to be fixed next snapshot. Attaching screenshot and updating description.

Please change the title to say “wrong-facing, rather than sideways, as several of the reports marked as duplicate get it for 180 degree rotated ones too.

Can confirm in 1.20.2 and 23w41a

Cannot confirm in 1.21. The portal simply does not activate.

Cannot reproduce in 1.21 either.

I was able to reproduce this in 1.21 with the setup shown in setup.png.

Relates to MC-207208.

The causes of this bug are:

  1.  Block pattern of end portal can be rotated.

  2. MC-207208: A frame that is not adjacent to the portal can also activate the portal.
