Error: tabs[i]._preview is undefined
When you have exactly 21 tabs and you close a tab, the AeroPeek object turns itself on. However it tries to turn itself on for the tab you've just closed, which doesn't work, because we've already deleted the preview. This leaves AeroPeek in an inconsistent state.
After removing the controller we check the preview count, and if the count drops to exactly 20 we enable AeroPeek, which tries to enable for the tab we're just deleting. The problem arises because we remove the controller after deleting the preview. If we remove the controller first, we will temporarily enable the preview, then re-disable it, and then the tab ordering gets updated.

This version simply skips tabs that have no preview, presuming that they're being deleted.
