Alex Harui commented on FLEX-33666:
-----------------------------------
MX datagrid would stop editing session when you touched outside the editor so
touching the scrollbar would the session and the editor could not be scrolled.
I'm pretty sure mouseWheel also cancels editing in MX DataGrid.
MX DG did not use scrollrect which also made scrolling the editor tricky. We
heard a few requests for keeping the editing session up when scrolling.
Spark DG may parent the editor where the it will be affected and then the
scrollrect should affect it. And if it doesn't, it might be interesting to see
what it would take to do it. But otherwise, it might be simpler to cancel the
edit session. There could be subtle usability issues if you can scroll the
editor offscreen and then type into it. Not sure what an accessibility screen
reader will do in that case.

> Create a simple editable Spark Datagrid that has enough lines to make the
> scroller appear. Click a cell to start it's editing session, then scroll the
> Datagrid using the mousewheel.
> The item Editor doesn't follow it's cell.
