Fabmaster: Missing static shapes from the Allegro board

Description

With many issues captured with a simple test board, I decided to look for issues with real boards. I used the attached Intel board: cds2f_Galileo_G87173_207_R01_fabH.zip

There was one unrouted net that is due to a zone (shape, in Allegro parlance) not being imported. But in the Allegro board it's not just any shape, it's a static shape.

A dynamic shape in Allegro voids vias and tracks and other copper elements of other nets. A static shape, on the other hand, does not. It always fills all area to it's boundary (outline). If a copper object of another net touches it, the shape doesn't move but a DRC is created. There are many niche uses for a static shape in Allegro.

The static shape connects U2A3 pin 6 and C2A3 pin 1. The net is VREF. Let's just look at Allegro, with the shape selected so the vertex handles are all visible and the shape properties opened:

I do see a shape in this area on the KiCad board, but it appears to be a huge shape covering the entire board on the top layer with no net assigned. So I don't think that's it.

The Fabmaster file appears to capture this shape. See line 97633 for an example of what appears to be a line of the right net and layer with one pair of vertices in the shape properties shown above in Allegro. I'm not sure what happened to this zone during import, but I'm not seeing it in the imported KiCad board.

There may not quite be an exact equivalent in KiCad to a static shape in Allegro, but a regular copper zone with a high priority might be the closest match (??). And if the zone isn't being created in KiCad now, I suppose anything is better than nothing.
