While editing in the built-in editor, I find that selecting text and then deleting it will reposition the cursor to the end of the previously selection area, rather than the intuitively correct, start of the deletion.

For example:

"This word is wrong."
'This is wrong".
select "word" and delete it, the cursor should be placed after the space following "This ", yet it is positioned at the 'w' in "wrong".
