Short description of error
With this combination of settings, to me the expected behaviour would be that the mesh shows in wireframe view, but the bone X-ray takes precedence over everything else - or put differently, the bones should be drawn on top of everything else.

Exact steps for others to reproduce the error

Simply open the attached file and try to select bones - you can, but it's unpleasant, since you're blind to what you're selecting.

This happens with both the "Show Bone X-Ray" overlay option and the "In Front" armature display option.
