[bug] Empty YAML Mapping Breaks Syntax Highlighting

[seandstewart]

Problem

Typing an empty yaml mapping breaks all subsequent syntax highlighting in the given file. If a file already has an empty mapping on load, it will highlight just fine, but if you add a single {, all highllighting after that line disappears.

I saw #5 and assumed this would fix the issue, however with the latest version of this extension, I'm still seeing the issue.

How to reproduce

Have a simple values.yaml like so:

key: value

When you open the file, it will provide correct highlighting. If you add another key with a mapping, syntax highlighting will break until you reload the workspace:

key: value
mapping: {}
