Intermittent Lint Error on Locally Referenced Files

[Russell Spence]

Describe the bug
I'm not getting Spectral Lint issues on locally referenced files when editing those local files. They seem to only occur when editing the root file, but disappear when editing other files.

To Reproduce

1. Have an OpenAPI yaml doc that contains:

paths:
  "/register":
    $ref: "authentication/paths/register.yaml"

2. Ensure that the file authentication/paths/register.yaml has a Lint issue in it.
3. Edit the root OpenAPI yaml doc in any way.
4. Undo the above edit.
5. Go to authentication/paths/register.yaml.
6. Notice the Lint issue is shown.
7. Edit authentication/paths/register.yaml in any way.
8. Undo the above edit.
9. Notice the Lint issue is no longer shown.

Expected behavior
Lint issues shown on locally referenced files at all times.
