stcpDiv element issues

Problem/Motivation

The div element with id="stcpDiv", which contains html/text copied by a site visitor, is visible. Moreover this element is displayed on top of the page.

Unfortunately, I can't attach a screenshot ATM, because this happened on our client's site.

Steps to reproduce

1. Open a page where sharethis is loaded. It's better shown on long pages.
2. Select any part of text/images/etc. and copy (either with Ctrl+C or via context menu).
3. Scroll to the top and see.

Proposed resolution

I don't how this element is supposed to be used or why it is not fully hidden (it only has style="position: absolute; top: -1999px; left: -1988px;"). So the proposed resolution is to be defined.

For now I'm going to hide this element with display: none !important on the client's website.

Remaining tasks

User interface changes

API changes

Data model changes
