[BUG] Hiding part of the mesh breaks orbit around selection

[theslams]

Retopoflow Version: 3.4.0

Blender Version/Hash: 3.6.1

Platform Version/Distribution: Windows 11

 

issue: After hiding part of a RF mesh, the view no longer orbits around the selection. It appears to orbit around an orbit point that includes the hidden part of the mesh in the selection (but I may be wrong about that part). I have provided screenshots and a blend file.

Screenshots:
Pic 1: My test object with a RF mesh on it. I have selected a vertex to one side. None of the RF mesh is hidden.
Pic 2: It rotates correctly around the selected vertex.
Pic 3: The same RF mesh as in Pics 1 & 2, but this time I have hidden one of the arms of the mesh. I have selected a single vertex on the other side.
Pic 4: The view does not orbit around the selected vertex. The orbit point is someplace other than the visible selection..

 

How to Reproduce:

1. Have a RF mesh.
2. Hide part of it.
3. Select a vertex.
4. Rotate the view.

Result: The view doesn't orbit around the selected vertex.
Expected: The view should orbit around the selected vertex.

Issue also exists in 3.4.1, but discovered a workaround: if you exit and reenter Retopoflow after hiding some target mesh, the orbit works as expected.
