Blocks incorrectly able to be placed on end portal frame / end portal frames are solid

Blocks incorrectly able to be place on top of end portal frames include: all doors, redstone dust, repeaters, and comparators, all pressure plates, all rails, all torches, pots, and all banners. This applies beds, cauldrons, etc. as well but this only matters in survival since you can place a frame under a block in creative.
