Not sure if just dragging the world directory from "saves" in to the attachement field is sufficient...

dropbox link?  https://www.dropbox.com/sh/y38msa5glrmwwvj/AAALvObittq1eVWH9g-vJ716a?dl=0

The Dropbox link would be better.

Just reproduced in my own test world, confirmed.

Seems to only be a visual glitch, rejoining the world fixes the issue.

Same thing has happened on mac high sierra for me. Platform-specific environment can be changed.

Same happened with me, but there was Overworld terrain in the Nether! I don't know whether these are the same glitch, but I reported on it and it was marked as a clone of this one. Hell = Earth???

Is this fixed in the latest snapshot (19w09a)?

I don't know it is fixed in 19w09a but we are unable to reproduce this bug.
