Describe the bug

The documentation examples in the Navbar section are broken. When a user triggers a collapse into a hamburger menu and then tries to expand the menu by clicking the hamburger icon, the UI breaks.

Expected behavior

There should not be multiple layers of text.

To Reproduce

1. Go to this link
2. Go to the first example
3. Make the navbar collapse by zooming in or making the browser behave like a phone/tablet.
4. Click on the hamburger menu
