Some circular shapes are rotated 90 degrees by default

Short description of error
Adding a mesh torus and geometry node circle primitive are rotated on z axis 90 degrees by default compared to other circular mesh and geometry node primitives.
Exact steps for others to reproduce the error
create a shape with 3 sides from torus, compare to shape with 3 sides made from cylinder, circle, UV sphere, cone. notice torus doesn't line up until rotated z 90 degrees.
geometry node, add primitive circle. join geometry with primitive cone, primitive cylinder, and primitive UV sphere. use the same value input for each primitive, increase the value from 3 to 12 and notice all primitives except the circle are uniformly changing.

Event Timeline

I tried to find this section in the source code but I've never looked at the code before so I couldn't find the section that describes how the primitives are drawn.

@Don Clark (samurai_shi) It would be very helpful if you could attach the test .blend file to the report (via drag & drop). Would that be possible?

Haha nice find! @Don Clark (samurai_shi)
Also nice animation!

I can confirm the rotated torus, when there are only 3 Major segments. It does seem a bit inconsistent with respect to other objects.
(I am not sure, it could be classified as a bug though)
