Bug - Sidebar - Hidden on smaller screens

Describe the problem
Sidebars will not be visible on the page when using a smaller screen and isManagedSidebar is false on the Page.

How do you reproduce the problem?
This can be seen on the PatternFly website: https://www.patternfly.org/components/page#vertical-navigation

1. Reduce the size of the browser window until the sidebar automatically closes
2. Click the hamburger button to try to open it again
3. The sidebar does not open

Expected behavior
The sidebar should appear on the page as it does when using isManagedSidebar on a small screen.

Is this issue blocking you?
We cannot update our mobile app to the newest version of PatternFly due to this.

• OS: Linux
• Browser: Firefox
• Version: 149.0.2

What is your product and what release date are you targeting?

Jira Issue: PF-4262

Start with the Page component and its sidebar behavior, then reproduce the issue from the PatternFly vertical navigation example by shrinking the browser and using the hamburger button. Done means the sidebar opens on a smaller screen when isManagedSidebar is false, matching the behavior when it is true.
