Unwanted element at the bottom of the single appointable product page

[Valentina R]

Only on single product pages for appointable products, an element with ID #ui-datepicker-div is placed at the bottom of the page. Because of padding, it is visible to the customer.

Not sure where this is coming from but it's only on appointable products.

This is a WP bug, but I'll add a fix with 4.4.9.3.
