Text highlighting for select and delete gesture previews

If there is a selection or deletion preview range set, then the corresponding highlight will be displayed, and the cursor or regular selection highlight will be hidden. Once the selection or deletion preview range is cleared, then the cursor or regular selection highlight will be displayed again.
