Transition between end stone texture and end portal frame is not as seamless as it previously was

In 1.13 and prior, the end portal frame reused part of the end stone texture for the bottom half, which caused it to seamlessly blend in. However, after the Texture Update, a significant break can be seen between the two blocks. I suspect that this is due to the End Stone texture being updated twice in 1.14's development, whereas the frame was only changed once.

A specific setup may need to be built as to mitigate the effects of MC-165504.
