Operating system: Windows 10 64 bit

Broken: 2.90.1 release, 2.92 alpha 165b4f85ec23
Short description of error
When "Optimal Display" in the Subdivision Surface modifier is enabled, only the edges of the original mesh are displayed in the wireframe.
Of course, when the modifier is applied regularly, the wireframe shows all edges of the resulting mesh.
However, if the modifier is applied by using Object > Convert To > Mesh, the wireframe is not updated and stays "sparse".
Exact steps for others to reproduce the error
- Open the file.
- In the 3d view header click on Object > Convert To > Mesh.
- Observe that the mesh still has a sparse wireframe.
- Enter Edit Mode and then switch back to Object Mode.
- Observe that the wireframe now displays all edges.
