Using git commit 1ac0b64d01f9cc3dcd5c722e9aa13b1b77c13056 (Lukáš Lalinský: Merge remote-tracking branch 'mineo/cluster-analyze')

When ctrl-clicking files or releases in the right pane of picard, in order to select multiple releases or multiple tracks within a release, it doesn't work correctly.

The first ctrl-click only moves the focus box (dotted grey border) to the item that you clicked on. If you ctrl-click again on the same item (once it's "focused"), then it is selected.

The expected behaviour is that ctrl-clicking on an item once would select it.
