dhtmlxForm tooltip doesnt appear to work

dhtmlx.com/docs/products/dhtmlxF … ltips.html

The above sample does not work in chrome 42. I do not see any tooltips.

Please advise.

Hello
Locally works fine in this browser version:

Thank you, I assumed it was when you hovered over the input field, not the label.

There is a note in documentation about it:
docs.dhtmlx.com/form__controls_l … uttextarea
tooltip - string, creates the tooltip for the input label
