CairoMakie has issues plotting 3D Rects with poly

[ranocha]

The code

julia> using CairoMakie

julia> poly(
               [
                       Rect(0.0, 0, 0, 1, 1, 2.5),
                       Rect(1.0, 0, 0, 1, 1, 1),
                       Rect(0.0, 1, 0, 1, 1, 1),
                       Rect(1.0, 1, 0, 1, 1, 1),
               ],
               color = 1:4
       )

produces the plot

The 3D rectangles are not shown correctly. I would have expected something like I get with a smaller size of the big one:

julia> poly(
               [
                       Rect(0.0, 0, 0, 1, 1, 2.4),
                       Rect(1.0, 0, 0, 1, 1, 1),
                       Rect(0.0, 1, 0, 1, 1, 1),
                       Rect(1.0, 1, 0, 1, 1, 1),
               ],
               color = 1:4
       )

• what version of Makie are you running? (]st -m Makie)

(jl_oQJ1ul) pkg> st -m Makie CairoMakie
  [13f3f980] CairoMakie v0.12.18

• can you reproduce the bug with a fresh environment ? (]activate --temp; add Makie)

Yes

• What platform + GPU are you on?
