ebay.com: Bookmarklet overlay doesn't cover page expansion.

[javanut]

eBay.com and sites like it will display more images if you scroll past the bottom of the page. If you activate the bookmarklet, the overlay only covers the original size of the page. If you scroll down past the end, more images from eBay will appear at the bottom, below the bookmarklet overlay.

The Pinterest bookmarklet seems to be able to extend the overlay over the page extension.

Steps to reproduce:

1. Browse to ebay.com
2. Launch bookmarklet.

Images appear in grid.
3) Scroll down past the end of the page.
4) More ebay images appear.
