Bug description

The problem initially occurred at Quarto books that I've been writing. After I make changes to a specific chapter and click 'Render', Quarto renders the document correctly, but RStudio does not show the new file in the viewer pane (the old one remains). It only updates when I stop the background job and render it again.

I tried changing every single piece of the yaml file to track down where the problem was but I was unsuccessful (which gave me a intuinton that the problem was not in that part). So I decided to create a new Quarto book project from scratch and add small changes to see when it would happen again.

Curiously the default Quarto book doesn't have this problem. But when I changed the default _quarto.yaml chapters part (code above), then the problem returned!

Also I noticed some things:

1. when _quarto.yaml is modified and changes saved, the document updates automatically
2. the problem doesn't happen in standalone documents

Steps to reproduce

1. Create a new Quarto Book project
2. Create a test.qmd file with one 'Test' h1 header
3. Change the default _quarto.yaml chapters part to

  chapters:
    - index.qmd

    - part: summary.qmd
      chapters: 
        - test.qmd

4. Open the test.qmd file and click on 'Render' button to run the current document
5. Change the header, write some text and render again

After this process only sidebar chapter title and breadcrumb should have changed (at least here)

Expected behavior

Changes should be addressed and displayed in the RStudio viewer panel.

Actual behavior

Changes are effectively made only after stop background job and render the document again.
