This prevents larger files from causing latency and lag, especially large YAML files, like generate Kubernetes menifests. This fix here simply does not enable highlighting indentation levels if the file is above 100KB in size. In my experience it's rare a file meant to be manually edited by a human is above 100KB in size.
