Creating a material that has it's tessellation mode set to "PN Triangles" and assigning it to an object results in the objects geometry to not properly display in Wireframe view mode. 



Tested in: 4.25 CL: 11062379

Steps to Reproduce
  1. Open the attached project and load "NewMap"
  2. Turn on Wireframe view if it is not already selected
  3. Select cubes placed in the scene

Result: The cube with the material "m_PN" attached to it does not accurately display its geometry when selected in wireframe mode.


Expected: The selected object to display the same geometry in wireframe view regardless of the materials tessellation mode.
