Docsify does not scroll to the clicked sidebar link content if the link was the last sidebar link clicked.

1. Visit the Markdown section on the docsify-themeable site
2. Click any section link (Ex: Code)
3. Scroll the page
4. Click the same section link

I believe the expectation is that docsify would scroll back to the section clicked.

Perhaps removing the hash from the URL, then updating it with the section hash would provide a quick fix?
