DRC: footprint doesn't match copy in library

Description

The DRC-check "footprint doesn't match copy in library" produces false results for some footprints on bottom side of board.

• seems to be affected by custom pad shapes
• could also be a footprint loading problem (during board loading)

Steps to reproduce

1. open attached project, open board: DRC_FP_different_01.zip
2. run DRC
3. get 2x "footprint doesn't match copy in library"-warning (see picture)
4. OK
5. update both footprints from library (both are contained in projectlibrary)
6. run DRC --> no error, good
7. save board, close kicad, reopen kicad, reopen board
8. rerun DRC: error is back (see picture again)
