At step 2 we see two sets of window controls, one drawn by Chromium and one in the top panel.
After step 3 we see two sets of window controls, one in the top panel, one in Chromium's titlebar.
When step 5 is executed we will find again that we have two sets of window controls, but this time one is drawn by Chromium and one by Unity.
At step 2: One set of window controls, the one drawn by Chromium.
At step 3: One set of window controls; in the top panel (Unity).
