Grass / Flowers / Snow are placed incorrectly in newly created chunks

Note

19/May21: This has now been fixed for everything except trees. For any remaining or reintroduced issues, please open new and specific reports with new repro steps.

The bug

World generation places tall grass/double tall grass, flowers/double flowers, sugar canes, snow, trees, and possibly other things in places it shouldn't.

Affected situations

Sand/gravel patches generated around water (lakes/rivers/oceans/etc) have things growing on them:

/tp @p 1250 67 10150
/tp @p 1230 70 10333
/tp @p -898 64 44766 but on seed 5384881648447775625

Lava and water lakes have floating plants and trees on top of them:

/tp @p 1100 66 10364
/tp @p 1111 66 10382
/tp @p 1636 63 11014
