3 Select Directional Light in Hierarchy and create Animation (by pressing "Add Property"in Animation Window)
4 Make NOT visible the Animation Window - tab, by opening some other tab
5 Select Main Camera in Hierarchy
6 Make visible the Animation Window - tab again
Actual Result: Animation Window still shows animation for Directional Light, but Main Camera is selected
