Edited Unassigned: [Designer] Toolbox link on empt designer surface doesn't work correctly [1455]

# REPRO
0. Visual Studio 2013 Preview (or latest), EF Tools latest, empty Console project.
1. Add new item, ADO.NET Entity Data Model, Empty Model
2. Make Toolbox "Auto-hide"
3. Click Toolbox.

# EXPECTED
Toolbox to pop up so that I can click/drag items.

# RESULT
Toolbox shows up and disappears quickly.

This does not repro for "Model Browser" link on the same surface.


__Note to triage: I don't think this bug needs to be fixed with EF6 - it can be punted to Future.__
