Model works when using rect().extrude(), hangs when using box() #698

To Reproduce

In the following, result0 will work fine, result1 will not perform the final cut and will not print "finished!".

import cadquery as cq
from cadquery.selectors import AreaNthSelector

result0 = (
    cq.Workplane("XY")
    .rect(20, 20)
    .extrude(10)
    .edges("|Z or <Z")
    .fillet(2)
    .faces(">Z")
    .shell(2)
    .faces(">Z")
    .wires(AreaNthSelector(-1))
    .toPending()
    .workplane()
    .offset2D(-1)
    .extrude(1)
    .faces(">Z[-2]")
    .wires(AreaNthSelector(0))
    .toPending()
    .workplane()
    .cutBlind(2)
)

print(f"rect -> extrude is valid? {result0.val().isValid()}")

result1 = (
    cq.Workplane("XY")
    .box(20, 20, 10, centered=(True, True, False))
    .edges("|Z or <Z")
    .fillet(2)
    .faces(">Z")
    .shell(2)
    .faces(">Z")
    .wires(AreaNthSelector(-1))
    .toPending()
    .workplane()
    .offset2D(-1)
    .extrude(1)
    .faces(">Z[-2]")
    .wires(AreaNthSelector(0))
    .toPending()
    .workplane()
)
print("about to cut")
result1 = (
    result1
    .cutBlind(2)
)
print("finished!")

I forgot to check before I submitted this; clean=False in the final cut prevents the hang.

Probably related to #660
