Short description of error
The procedure for copying Materials, which is order-sensitive, seems to have the order reversed depending on if the user selects Objects in the 3d viewport or the Outliner
Exact steps for others to reproduce the error
Make a black cube
Make a blue sphere. Separate them so you can see them both.
Select both one order in the 3d viewport.
CTRL-L to copy Materials. Note the result. UNDO.
Select IN THE SAME ORDER in the Outliner.
CTRL-L to copy Materials. Note the result.
100% here, in one case, the first item is copied FROM.
In the other, the second item is copied FROM.
The order selection in the viewport and the outliner should have the same results.
