TinyMCE wpView:
- When a view is selected, pressing the up or down arrow key should move the caret to the block above or below the view.
- Selecting some text that touches the view and deleting it should not remove part of the view.
- Show/hide the "fake" carets on editor focus/blur.
- Don't create new paragraphs before or after a view on pressing the arrow keys or delete key. Paragraphs are created on pressing Enter.
