Footprint editor does not retain "SMD Aperture" setting when placing subsequent pads

Steps to reproduce:

• Create or open a footprint
• Place a pad, edit it to be an SMD Aperture, rest of the pad definition doesn't matter
• Place another pad

Expected Result: Another "SMD Aperture" with the same settings

Actual Result: An "SMD" Pad with (apart from that) the same settings
