Inconsistent behavior open/close automation lanes - and resetting filter for track and bus

When open and close automation lanes of track - filter is always restored to Clips when closed
Consistent with this also highlighted automation curve restored to dark ghost
 
When doing the same on a bus - filter remains as selected, in this case reverb send
Inconsistent with this - automation curve is restored to dark unselected curve, even though an automation is still selected in selectionbox
I have to select none, and then back to the automation, in this case reverb send - to get highlighted automation like selection box says.
 
So Sonar thinks it's done like tracks behave - but filter selection is not changed.
 
Can anyone reproduce?
 
Since busses does not contain clips, there is no clips filter(haven't checked frozen stuff).
 
So either
a) for busses change selectionbox to show none, reset kind of like tracks do?
b) or automation curve selected is drawn in selected state
 
 
Overall, I don't like that closing automation lanes should reset filter at all - why should it.
What do you think?
 
Thanks.
