Comment 1 for bug 1760097

This is kind of just how the DRC works (for now), don't think it would be easy to fix for V5.
"Test zones" step of DRC doesn't actually check for collisions between tracks and zones, only checks for zone-to-zone collisions and that zones get valid netcodes.
So, the only way to get a DRC-passing board is to enable that checkbox to refill zones before running DRC.
