List: range selection should update focused element

[Tyriar]

Current behavior looks a little weird imo:

I think the reason behind this is because the original item is important as it is the root item if the user shift+clicks elsewhere. But even so, the last clicked item is probably more important at this point. I suggest we move to what Windows explorer does and highlight the item that was most recently clicked:

This is hard to implement without introducing yet another trait in the list...

Also, aligning with Windows should not be our goal, but just provide a consistent experience. What does Finder do?

Yes aligning with Windows Explorer isn't the goal, making it functionality and as users expect is. Windows Explorer happens to have maintained a tree view for decades so it's a good point of reference.
