Thanks, Alex. I don't know if there's a bug, per se. As I mentioned in my first post, I only had an issue when losing focus to something outside the grid. I may have a workable solution which is hopefully not too ugly:
- on itemEditEnd, call preventDefault, and re-activate the editor using editedItemPosition - in the editor, override setFocus and call the validator I haven't tested this with scrolling.
