Highlighted slur spanning multiple systems

Noticed that when in note-entry mode and starting a slur, if the slur spans more than one system, the slur on the next system no longer shows highlighted color (blue default) while continuing to input notes. This can be slightly misleading to the visual-oriented user, as there's no longer any visual cue as to whether or not the user has pressed the 's' shortcut again to finalize the slur as normally occurs when dealing with only one system.
