Oh, sorry- I am just saying don't expect the same behavior from 2 different editors (like don't expect Windows 7 behavior in Windows 10).

I would love it if they made improvements on Source Editor (it still leaves something to be desired), because I do still prefer the retired Source Editor. I just don't see them making custom improvements in a preview mode but won't object if they do if it betters the editing experience!
