Short description of error
Clicking in the UV editor *always* results in a selection regardless of how far away from an element you are, and regardless of what the "Deselect on Nothing" property is set to in the uv.select operator.
Exact steps for others to reproduce the error
Zoom far out in the uv editor and click in some void area where you would not expect to be able to select something. Observe that element selection works regardless of distance.
