Unity dash doesn't minimize

[Laryllan]

Binary package hint: unity

The Unity dash doesn't minimize open programs.

Try for yourself:
1. Open Firefox using the dash on the left hand side of the screen by clicking on it again
2. Click the Firefox icon again.
Nothing will happen.

I believe this is huge usability setback, as I expect at least _something_ to happen when I click on the programs icon again.
It simply should minimize like in the default gnome interface lower panel.

This is regression.

Thanks for your time,
please consider this.
