Anjuta cannot use scroll wheel to scroll up when using Scintilla editor

[Sebastian Geiger]

Since the upgrade to precise I cannot use the Scintilla Editor plugin anymore. When I select it, the scroll wheel on the mouse is no longer able to scroll up (but I can still scroll down).

Triggering the scroll wheel lets the editor content flicker, but it stays at the same position.

When I use Gtksourceview then everything is fine.
