Short description of error
If an object has mirror modifier enabled and wireframe is enabled in overlays, in edit mode edge selection highlight looks to be drawn under the black wireframe.

Exact steps for others to reproduce the error

  1. Open attached file
  2. Select edges and notice that the selection highlight color is almost invisible

Event Timeline

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:
