Ghost blocks appearing when blocks changed occur on edge of view distance

Partner Rank: 1
No workaround is known.

Verification builds:
Was only noticed in 1.16.200+ specifically 1.16.200.53

Summary:
Ghost blocks appearing when block changed occur on edge of view distance

Impact:
Blocks being displayed that arent there is a fundamental failure of a voxel based game. It greatly impacts Jigarbov Holiday map.

Repro Steps:

Simply playing the map will show the issue over time with a low render distance. There is another repro which appears to be the same issue:

  1. Open the holiday world
  2. start the game (creates tickingareas and stuff) but dont complete the tutorial
  3. run this command /fill 271 66 191 240 68 80 stone
  4. if bug doesnt happen, run again /fill 271 75 191 240 82 80 stone

Observed Results:
sections of blocks are missing entirely_. they act like they are not there , when right clicked with open hand they appear, player can jump through them. reloading the game makes them appear._

Expected Results:
when block changes are made on the server they should be reflected on the client.

note: the entire play field is in a ticking area.

Videos shared: yes, on slack

Regression Build:
1.16.100.04
