Code Editor 2: Inconsistent autocomplete in large document

[KormexGit]

Description

In my main project, autocomplete will randomly include or not include instance variables as I type out the variable name. This seems to only happen in objects with a ton of code/variables, as it doesn't happen in the majority of my objects, even ones with hundreds of lines in create.

This also only seems to happen when typing in the create event. It doesn't happen when I type the same variable names in another event.

Steps To Reproduce

1. Open attached project
2. Open oPlayer
3. Scroll to line 2090 of create
4. Try typing rush, or typing the name of any of the variables shown above
5. See that autocomplete will swap between showing or not showing the variables as you type each letter

This ticket is the result of poor parse performance. The location identified as problematic triggers a significant amount of background reparse work which takes longer than the timeout period for filling the code completion list.
