Comment (by rixeo):

 - In the WordPress admin backend, navigate to Appearance > Menus
 - Select a menu that shows in the "Primary Menu" Display Location. If
 there is no new menu, create a new one and assign is to the "Primary Menu"
 under Display Location
 - Under the "Add menu items" section, expand the sub-section "Custom
 Links"
 - In the field URL, add something like `#test`
 - In the Field Link Text ass something like "Sample Link"
 - Click the Button `Add To Menu` to add the item to your menu
 - Click `Save Menu` which should be on the right near the bottom
 - Visit your WordPress site frontend and click on the custom link
 - Open your browser console
 (https://balsamiq.com/support/faqs/browserconsole/), select the console
 tab
 - Now click the custom link in the navigation menu
 - Before the fix, there should be an error shown in the browser console
 that starts with : `Uncaught TypeError: anchor is null`

 Clicking it on the frontend will trigger the error

 > The term "custom hash" may be unfamiliar for contributors. I assume it's
 referring to an anchor that links to specific spot in a web page. Is this
 correct?
 >
 > What could be helpful is to provide the setup instructions that guide
 testers to prepare for testing when a "custom hash" exists and when it
 doesn't exist.
