Filled zones ignore clearance setting of pads without net
Description
It seems that since recently, filled zones ignore the clearance setting of some pads.
For example, I've got this fiducial marker with solder mask clearance 0.3 mm and pad clearance 0.5 mm but the GNDD fill ignores the clearance settings.
