[BUG] Pyret editor context load sync issue

[anzook]

Bug Description
'use context essentials2021' load can cause sync issues by appending a different number of lines in connected editors

To Reproduce
Steps to reproduce the behavior:

• load a VMT Pyret Room
• Load a VMT follower room
• If one has more lines of code than the other, sync can be corrupted by starting code on a further line than the follower.
  ex: One user writes code on line 3, the other sees it on line 2. Further edits are then likely to break as the line reference is off

Expected behavior
editors should load to the same point.

Would this also fix code persistence on reloading the room/editor?
