Vibrant Visuals: Nether/End portal blocks rendered in front of water.

Please see the pictures.

This doesn’t happen when Vibrant Visuals is off.

Edit:

Glass, glass panes and all their stained variants also have theis issue according to MCPE-219726.

Slime blocks, honey blocks and all variants of copper grates also have this issue.

Hardened glass, hardened glass panes and all their stained variants and heat blocks from Education Edition also have this issue, too.

Unlike slime mob, all of the blocks mentioned here only render in front of water when Vibrant Visuals is enabled.
