banner and sidebars

Bug description

When using a sidebar menu in hybrid navigation without bread-crumbs, the title of the content referenced in the sidebar is not placed inside the banner in mobile width.
Using bread-crumbs brings the correct behavior.

Steps to reproduce

_quarto.yml

project:
  type: website

website:
  title: "banner"
  bread-crumbs: false 
  navbar:
    left:
      - href: index.qmd
        text: Home
      - sidebar:sidebar
      
  sidebar:
    - id: sidebar
      title: sidebar
      contents: 
        - text: content1
          file: content1.qmd

format:
  html:
    theme: cosmo
    css: styles.css
    toc: true
    title-block-banner: 966-600x200.jpg

Reproduce the mobile-width layout from _quarto.yml using index.qmd, content1.qmd, and styles.css, with bread-crumbs disabled and title-block-banner enabled. Compare the sidebar-linked content page with the expected banner behavior. Done means the content1 title appears above and inside the banner without requiring bread-crumbs.
