[NTG-context] [***SPAM***] Background color with dotted frame formula

Here is the same mkiv macros showing three specimens. #1 is stand rounded gray background. This works #2 The grey background seems to not go up to the dotted frame of the frame is too high? #3 The dotted frame does not show up at all. Here is the mkiv file: Thanks
