2 fast clicks in different areas count as double click

[Robert Dyer]

When switching workspaces, you must double click on a workspace in order for Expo to switch to it. However, a single click on one workspace followed by a very fast single click on a different workspace counts as a double click on that 2nd workspace.

Steps to reproduce:

1) start in the top-left workspace
2) start Expo (In Unity, <super>-s)
3) single click on the top-right workspace
4) very quickly after step 3, single click on the bottom-right workspace

Expected behavior: still in Expo mode, bottom-right workspace highlighted

Observed behavior: not in Expo mode, bottom-right workspace is current workspace
