Subject: [PATCH] Fix macro list / macro edit area splitter resizing

When horizontally large widgets (e.g. the Window condition) were part of
the currently selected macro moving the splitter would result in it
either fully hiding the macro list or the macro edit area.

Now the list and edit area can be resized smoothly.
