I noticed that when you select an item, it highlights both that item and the column header.  I assumed this was a new feature but wonder if it's related to the following behavior:

 

1) Select item.

2) Paste text (ctrl-v)

3) Text is pasted, but the grid view switches to the top of the grid.

 

I've confirmed this multiple times in two files.  Note: it only occurs if you're in cell select mode.  If you double-click to enter edit mode, the text pastes correctly without the view switching to the top of the screen
