Code disappears

Hi guys.

I have created a web widget so that people can add badges through html to their websites but when I want to select the code, the code disappears. Almost as if the code in the box is a label and not text. I have posted on the webwidget moduel and the maintainer says that it is the theme. He says;

@besnikt your theme is doing that :onfocus emptying the field which is a little weird.

function() {
  if (this.value == this.defaultValue) {
    this.value = "";
  }
}

in jollyness.js

The relevant form output can be seen on http://oflocal.co.za/cape-town/top10-best-beaches in the right sidebar under the "badge"

Please can someone explain how to fix this.

Thanks
