If you tap to nearly the end of an editeng paragraph, then drag the
cursor using EditView::SetCursorLogicPosition(bPoint=true,
bClearMark=true) to the end of the paragraph, finally hit enter, the
text between the tap position and the end of the paragraph gets deleted.

Fix this by calling GetEditSelection() after DeselectAll(), so that the
original cursor position (before the drag started) never survives, which
gives back the lost text, too.
