Title Class=email causes Social icon png to fill field

I wish I could be clearer than that… let me see if I can clarify.

You can see it in action here, but it happens with the Jetpack contact form as well as anything else that uses the “email” class.

When there is a field on my site with the title class of “email” the full size Social png is inserted into the text field. The visitor can still type inside the box, though it is nigh impossible to see what you’re typing.

Disabling the Social plugin does not change this behavior.

For example, in the form I referenced above, if you inspect the code, you see the following html:
<input type="text" title="" class=" required email ee-reg-page-questions ee-reg-page-text-input " id="email-2-0-1" name="email" value="">

This invariably results in a text field that looks like:
Email* |**INSERTIMAGEHERE** |

In Safari, I’m able to make small changes to the live webpage code, so I noticed if I change the above code to this:
<input type="text" title="" class=" required email1 ee-reg-page-questions ee-reg-page-text-input " id="email-2-0-1" name="email" value="">

The image disappears and all is well.

I have dug through the CSS and even some of my plugins and cannot find a direct reference to a class for email that would embed the picture…

I’m stumped. Does anyone have any ideas?
