PEP-rounded drawings can leave a contour 1e-6 short of closing. ShapeBuilder
chains it as a loop at Tolerance.ChainTolerance, but the slide classifier
re-recovered loops at 1e-7, so the whole part became unresolved and every
contact with it blocked. Parts placed in its cutout at exactly the part
spacing could not be pushed (Y/X keys) in any direction, even away from the
wall. Recover loops with the same tolerance ShapeBuilder uses.
