Short description of error
Wireframe doesn't update in viewport after applying subsurf with optimal display enabled.

Exact steps for others to reproduce the error
1: Add suburf modifier to default cube
2: Make viewport setting to like 4
3: Enable wireframe and all edges
4: Enable "Optimal Display" on subsurf modifier
5: Apply modifier

Can enter edit mode and then back to object mode to update wireframe.

Confirmed on current master (03f652b2c1).

I tried adding WM_event_add_notifier(C, NC_GEOM | ND_DATA, ob->data); and DEG_id_tag_update((ID *)ob->data, ID_RECALC_GEOMETRY); to the modifier_apply_exec() function, but that didn't solve it. You can even switch between Rendered/Solid/LookDev/Wireframe, or enable/disable drawing of overlays, and it'll still keep drawing the "Optimal Display" subdivision view.

Wireframe overlay doesn't apply to Subdiv if added right after mirror modifier either.

Mirror Modifier (Clipping)
Subdiv Modifier

You can put Subdiv first to get the Wireframe, but then mirror clipping doesn't work because mirror has to be first.

This may not be related, if not I'll make a new bug task.

The control edges are provided by subsurf modifier and stored in the mesh. During drawing the draw engine still sees and uses the data.

Solution would be to clean up these control data after applying the subsurf modifier so the base mesh doesn't have the data.
