Baking a NavigationMesh for HeightMapShape creates incorrect NavMesh

[rustwork]

Godot version

4.0.2.stable

System information

Windows 10, Vulkan, Nvidia RTX 3060 Ti

Issue description

When baking a NavMesh from code for a StaticBody3D that has a HeightMapShape as its Shape, the resulting navmesh is offset and skewed strangely.

Here's a simple example where a radial gradient image is used to generate cone shaped collision for a HeightMapShape. As you can see the navmesh is offset and distorted compared to the collision.

Steps to reproduce

Please see the Minimal Repro project attached below.
When you run it, you can move the debug camera with WASD and rotate it by holding down the right mouse button.

The project is structured like this:

Note: The Parsed Geometry Type of the NavigationMesh is set to Static Colliders

The script on the root node generates collision from an image and then bakes the navmesh.
