SysML port size changes unmotivated

[PeterHeintz]

When you have a port within a block and you assign a stereotype to it AND the stereotype changes the color appearance (in my case defined in a MDG) the default port size changes from 5mm x 5 mm to roundabout 20 mm x 30 mm.
A stereotype only defining change in color should not change the size!

You've probably exported the size of your stereotype element on the diagram as the size of of the stereotype. Explicitly specifying the size or unchecking the export of size should help.
