Glitch in Fassungsansicht: Dreissiger get loaded on scroll, ignoring load-buttons

[vvvyyynet]

I'm experiencing this regularily now, but I don't know where it comes from: When I scroll in one of the Dreissiger (most of the time I use the first column) I reach the load-button, but before I can click it, the next Dreissiger gets loaded and the button disappears.

• happens in both directions
• does not happen all the time
• happens on different zoom-levels
• happens on two-finger scroll and with middle-click+red lenovo-button
• happens on slow and fast scroll

Not sure whether this is related to #45.
