Scroller breaks SearchPanes (Button Initialisation)

root66

Link to test case: https://jsfiddle.net/d2q469uy/
Debugger code (debug.datatables.net): -
Error messages shown: No errors
Description of problem: As soon as I include the scroller extension (I don't need it in the example, but in the real script), no more entries are displayed in the SearchPanes after a certain line number (when using the button initialization). But the scrollbar suggests that there are many more. If I search for e.g. "Tiger Nixon 175", the entry is displayed. Without a search entry, "Tiger Nixon 175" is missing in the list.

Also, there is a 0 at the end of each filter list.
