Fold should not open when your cursor is over it

[peey]

Describe the bug
In vim, folds don't open even if your cursor is over the ... fold element. It only opens if you open it explicitly (e.g. zO)

To Reproduce
Steps to reproduce the behavior:

1. Make a new JavaScript file
2. Write a function
3. Fold the function body
4. Bring your cursor to the fold. Or just try to navigate to line below folded function using j.

Expected behavior
Fold shouldn't open.

Environment (please complete the following information):

• Extension (VsCodeVim) version: 1.15.0
• VSCode version: 1.47.0
• OS: Ubuntu 20.04

Duplicate of #1004, this is a result of VSCode's insufficient folding API. Try enabling foldfix; it's hacky and has other bugs, but it should resolve this particular issue
