Error messages slide down twice?

Hi,

When you try and submit a form with none of the fields filled in, the error messages slide down, it scrolls to the top of the form, and then the error messages slide up and down again. Ideally they’d just slide down the once.

This happens on a dev site I’m working on, as well as the demo:

Any ideas why this is happening?

Thanks,
James
