[Plugin: WordPress Google Form] Keep the red asterisk

Adding the SPAN tag to the list of allowed HTML elements is certainly possible but I am not sure it is necessary. When I look at the page source for a couple of Google Forms, for example my Help and Support Form, the text is red and the HTML looks like this:

<div class="ss-required-asterisk">* Required</div>

The CSS supplied with WordPress Google Form defines this:

div.ss-required-asterisk {
    color: red;
    font-weight: bold;
}

The default CSS isn’t enabled unless explicitly turned on the WordPress Google Forms settings page.

Am I missing something?
