Trace.Capsule gives invalid results when flat on the Z axis

[dotryen]

Describe the bug

Trace.Capsule returns invalid/bad results when the capsule is flat on the Z axis.
From my testing, bad results only happen on mesh surfaces parallel to the Z axis.

To Reproduce

1. Create a mesh box
2. Create a script to cast flat capsules
3. Use the script and try different angles and capsule properties

Expected behavior

The capsule traces properly intersect and collider with surfaces.

what's invalid about them?

Ah I probably should've explained the example video. The yellow circles are my character's collider (just the ends) and they can end up inside surfaces. I found this to only happen while having the capsule be flat on the Z axis. I've also tested it outside of a character controller context and tested just the trace alone. The flat capsule traces tend to have edge cases where they don't detect surfaces properly.
