Heading field not required when checked in field settings

Problem/Motivation

We've been using this module on any of our sites, but only now are finally in the situation where we want the field to be required. Upon checking the required box when creating the field, nothing shows visually on the front-end indicating the field is required (*) and the field will let you save without any data.

Proposed resolution

It seems that by checking the value of the element required setting in the widget file it solves this problem easily.

Remaining tasks

I've created a patch, am going to test with a few of out sites to ensure it works as expected then attach it in a follow up post.
