Describe the bug
Mouse selection of atoms does not work for the wireframe molecular representation. (It does work for e.g. ball and stick.)

To Reproduce
Steps to reproduce the behavior:

1. Load a molecule as a PDB file
2. Click on Selection Tool
3. Use left mouse button to drag and in principle select some atoms onscreen
4. No atoms are highlighted. Clicking the Delete key does not delete the atoms that should have been selected

Expected behavior
Selection of atoms with mouse should work in wireframe representation

Thanks, I can confirm. Wireframe will show selected atoms (e.g., select by element or residue commands) but not the selection tool.

I'll look into this soon.

Thanks for looking into this!

This was an easy one. Seeing the issue pop up, I knew where the bug would be.

On the other hand, it exposed a much weirder selection bug (#1129).
