Bug Report

Steps to reproduce

1. View the site https://hibbitts-design.github.io/docsify-template-v5/#/ on mobile
2. Open the sidebar
3. Tap on ReadMe to view page sub-topics (as expected)
4. Tap on a ReadMe sub-topic to view that sub-topic on page (as expected)
5. Open the sidebar
6. Tap on Second Page (with no sub-topics), and while the page is navigated to the Sidebar remains open (not expected, as shown below)

Here is an additional Docsify v5 rc-1 example (tap on Topic One and Topic two when on mobile):

And the issue also is evident when mergeNavbar is used (tap on Sidebar to view merged Navbar items when on mobile):
