`Bridge` returns `NaN`s for `PolyArea` with intersecting `Ring`s

I was trying to do a geojoin involving United States census block level data, and ran into an error. I tracked it down to a specific geometry, where calling simplexify would introduce NaN into the vertices. I have created a minimum working example below.

julia> ring1 = Ring(
               Point(0., 0.),
               Point(0., 3.),
               Point(2., 3.),
               Point(2., 2.),
               Point(3., 2.),
               Point(3., 0.)
           );

julia> ring2 = Ring(
               Point(1., 1.),
               Point(1., 2.),
               Point(2., 2.),
               Point(2., 1.)
           );

julia> pa = PolyArea(ring1, ring2);

julia> simplexify(pa)
10 SimpleMesh{2,Float64}
  10 vertices
  ├─ Point(0.0, 0.0)
  ├─ Point(0.0, 3.0)
  ├─ Point(2.0, 3.0)
  ├─ Point(NaN, NaN)
  ├─ Point(NaN, NaN)
  ├─ Point(1.0, 2.0)
  ├─ Point(1.0, 1.0)
  ├─ Point(2.0, 1.0)
  ├─ Point(3.0, 2.0)
  └─ Point(3.0, 0.0)
  10 elements
  ├─ Triangle(7, 1, 2)
  ├─ Triangle(6, 2, 3)
  ├─ Triangle(5, 6, 3)
  ├─ Triangle(3, 4, 5)
  ├─ Triangle(6, 7, 2)
  ├─ Triangle(10, 1, 7)
  ├─ Triangle(10, 7, 8)
  ├─ Triangle(10, 8, 5)
  ├─ Triangle(9, 10, 5)
  └─ Triangle(5, 4, 9)

Note the NaN's in the list of vertices above.
