Object highlighting while selecting not always working

Hi Guys
See attached video.
Selection from groups holding ctrl+shift.

I’ve noticed this has been changed since Rhino 5 and perhaps 6 in that face or group object selection often relies on clicking exactly on a surface isocurve, which are invisible unless you change the display mode to show isocurves.

I’ve noticed that it happens when object is in Ghosted mode or anything that involves transparency.
