Width point paramter collapses too quickly

Hi,
I’m running synfig studio 1.5.0 fairly successfully. However, there is one very irritating feature and I wonder whether it’s intentionally like that. Whenever I edit in the parameter list of an advanced spline curve within the width point complex it immediately collapses afterwards. To make further changes I have to open it again. Is that wanted?

Does it happen only when you create the first waypoint in that particular width point, right?

Yes, I think you’re right. But why is that necessary?

Not necessary, but we have to fix it yet.
