Weird looking of end portal and end gateway when seen through lava

When you're looking on end portal through lava, it will be colored yellow instead of moving colorful dots. Also when you're looking on end gateway through lava, it is not shaded with the red color.

What I excpect:
I should see its normal appearance shaded with the red color.

What actually happened:
The end portal is colored yellow and the end gateway is not shaded at all, just like its normal appearance.

To reproduce:
1. Place an end portal block. Use /setblock to do it
2. Put a lava 2 blocks above it, and wait until the portal is flown by lava
3. Get in and look at the end portal. The bug is reproduced. Also to test the end gateway block, use setblock to replace the end portal.
