[Koha-patches] [PATCH] Bug 7466 - Cart notification popup should appear onscreen even when button isn't

[Owen Leonard]

This patch compares the scroll position of the window with the page
position of the cart button and displays the cart notification
popup at the top of the visible page if the cart button has moved
offscreen.

Includes fix for OPAC and staff client.
