Bug: ExtendSrf flips BrepFace's normal

Rhino Rhino for Windows

8.8.24163.12481, 2024-06-11

_ExtendSrf flips the BrepFace’s normal when it is opposite of the underlying surface’s natural normal (+w). This occurs for both Type=Smooth and Line. When Merge=No, only the new face is flipped relative to the input face.

7.37.24107.15001, 2024-04-16 does not do this.
