Multiple portals can overlap and cause glitched block

Creating two portals which will spawn overlapping each other is now possible. Works with any size, even if portals are the default old 4*6 size.

The part where the two portals overlap will turn invisible, but still has a wireframe when moused over. The direction will match with one portal, but not the other.

I expected this to either stop the second portal from being created (as portal blocks are in the way when you make it) or create a cross shaped nether portal block to fill the middle without looking glitchy.

Also, it seems that you can remove the obsidian blocks on the side that these invisible portal blocks are not pointing in to, and both portals will stay. But if you remove the obsidian on the side that the invisible portal blocks are pointing into, both portals will go.

This is not a duplicate, MC-30796 is a completely different issue. Please can a mod reopen.

This is not a duplicate of MC-30796 if I'm understanding correctly. This actually creates glitched out blocks that both portals rely on, where as MC-30796 is more similar to lava not rendering sides when against ice.

This can create portals without sides, actually intersecting portals and the point where they intersect is invisible and incorrectly rotated blocks. MC-30796 is just a render bug.

After discussing it with fellow staff, it has been deemed that both these reports are caused by the same issue. In both of these cases the bug is caused by connected portal "blocks", either in parallel or perpendicular.

The turning invisible part may be caused by the same issue, although I intended this bug report to be more about the fact portals can intersect and glitch out. Even if it didn't turn invisible this issue would still be present as there's no nether portal block for this situation, and the other report doesn't seem to mention this anywhere at all.

Should I create a new report for this bug and leave out the fact it turns invisible? Or ask for it to be added onto the other report?

You are able to create portals with just 4 obsidian using this bug, or portals with messed up directions, so it is definitely something that should be fixed rather than just fixing the rendering of the portal blocks.
