The mobile menu vertical scroll issue with application shell 4

The community member is building a new page using 'Application Shell 4' and is experiencing an issue with the mobile menu vertical scroll. On desktop, the scroll works perfectly in the left panel, but when viewing the site in mobile view and opening the mobile menu, the community member is unable to scroll down in the same way - only the background scrolls. The community member is asking for ideas to resolve this issue.

In the comments, another community member requests a read-only link, and the original poster says they will share it when they are back in the office on Monday. The original poster then shares a read-only link to the site preview.
