Steps to Reproduce:

1. generate large yaml file (kubectl get all --all-namespaces > large-yaml.yaml)
2. highlighting breaks (note line numbers for relative size, also node sidebar):
   

I am unsure if it is a plugin issue or a vscode issue, please advise.

There's a maximum number of lines we colorize. That's for performance reasons.
To check if that applies here, open the dev tools (Help > Toggle Developer Tools) and check the console log. We print a message when the size limit has been applied.
