Getting file not found errror when setting `revealjs` setting

Bug description

In my _quarto.yml file, if I add these options:

format:
  html:
    code-copy: true
    theme: cosmo
    css: styles.css
+  revealjs: 
+    code-line-numbers: false

I get the following error

ERROR: NotFound: No such file or directory (os error 2), rename '/Users/hamel/github/embed-debug-quarto/1_setup/index.html' -> '/Users/hamel/github/embed-debug-quarto/_site/1_setup/index.html'

Clone the linked minimal reproduction and run quarto render with Quarto 1.3.450. Start from the format configuration in _quarto.yml and trace the render step that renames 1_setup/index.html into _site; done means the project renders successfully with both html and revealjs settings enabled.
