Graphics Custom shaders and wireframes

My custom CG shaders no longer show proper wireframes in scene view when selected but instead the wireframes appear as the UVs at origin.

I'm obviously missing something in my shaders, any pointers what to look for? I can't finding anything too relevant in the docs and it has made using the scene view quite annoying.

 

Aaaand I figured it out.

I had a custom meta pass in my shaders and I had it first in the shader (before the normal pass) and that's what was triggering the above behavior.
