[26.1 | Shaders] blockEntityId does not work on end portals

[GeForceLegend]

Description of Issue

blockEntityId on end portals is -1 even when it's set to some value in block.properties. I'm not sure if it works on other block entities.

Steps to Reproduce

1. Load any shader that do custom rendering on end portal
2. See end portals just looks like default treat on Optifine
