Describe the bug

First of all, thank you for your great work!
I just noticed a bug in Documentation part in Form helpers page. You indicated on the related page as below:

Use an input helper to display additional information about a form element. The text label will appear once a user hovers over the helper.

But does not work. Notthing happens. I hope I am not missing something. You can see the screenshot as below without cursor.

Tested Device

• Browser Google Chrome
