Details

On mobile devices (window width < 960px), navigating to the homepage via the sidebar navigation causes the page to become unscrollable.

Steps to reproduce:

1. Open the page on a screen with a width < 960px.
2. Open the sidebar (typically by clicking a menu icon).
3. Navigate to the homepage via the sidebar link.
4. Attempt to scroll down the page.

Expected behavior: The page should be scrollable after navigating via the sidebar, allowing users to access all content.

Observed behavior: The page is unscrollable, preventing users from seeing content below the initial viewport.

Reproduce Steps

rspress_error_00.mp4

1. I have attempted to reproduce this issue in Chrome's incognito mode with all browser extensions disabled, but not record a video.
2. My video recording tool doesn't show mouse wheel up/down scrolling.
3. Note that the URL after navigating to the homepage from the sidebar includes "/index". Refreshing the page (F5) removes "/index" from the URL, and the page then scrolls normally.
