Describe the bug
A clear and concise description of what the bug is.

To Reproduce
Steps to reproduce the behavior:

1. Create & commit the following workflow:

   # yaml-language-server: $schema=https://json.schemastore.org/github-workflow.json
   name: Build
   
   on:
     pull_request:
       branches:
         - main
   
   permissions:
     contents: read
   
   jobs:
     build:
       name: Build
       runs-on: ubuntu-latest
       outputs:
         build_id: ${{ steps.build.build_id }}
       steps:
         - name: Checkout
           uses: actions/checkout@b4ffde65f46336ab88eb53be808477a3936bae11 # v4.1.1
           with:
             show-progress: false
   
         - name: Build
           id: build
           shell: bash
           run: |
             echo "Building"
             echo "build_id=12345" >> "$GITHUB_OUTPUT"
   

2. Notice the linting warning on ${{ steps.build.build_id }}: Context access might be invalid: build_id.

3. Delete the following lines, save but do NOT commit:

       outputs:
         build_id: ${{ steps.build.build_id }}

4. In the diff window compare the changes

5. (BUG 1) (while diff is open) Notice the LEFT window showing the linting warning, which also shows up under 'PROBLEMS'

   

6. (while diff is open) Double click the warning under problems and notice it opens a locked (denoted the padlock next to the name) version of the previous, unedited version of build.yaml.

   

7. Close the diff & locked old version of build.yaml

8. (BUG 2) Notice the linting error is still there under 'PROBLEMS'

   

9. (BUG 2 related) When double clicking linting warning it opens up the same locked (denoted the padlock next to the name) version of the previous, unedited version of build.yaml.

10. (BUG 1) Now when hitting 'CTRL+P' to switch between files there are 2 entries for build.yaml which are indistinguishable, yet refer to different versions:

    

Expected behavior
Only errors on the new version are reported.
