nav-tab anchors does not work when starting with numbers

Created by: yannickpschroeder

A client of mine uses nav-tabs to navigate through products of a specific category. Some of the product names start with a number. I added an code example which uses the example from https://getbootstrap.com/docs/4.0/components/navs/#javascript-behavior . I just edited the first tab using the anchor id 1home instead of home and the tab will not be activated anymore.
