Short description of error

The same is happening with other modifiers. Essentially every modifier that preserves the original edges has this problem. Using "Adjust edit cage to modifier result" on the modifier fixes the problem with the side effect of being able to select generated edges.

My guess is that the wireframe for the resulting mesh would have to be drawn before the wireframe of the original mesh.

Without wireframe:

With wireframe:

I am still getting this issue!
Only when modifier is active. Happens with multiple edges selected too.
