Editor: Skip auto completed character only if it was recently inserted.

This means you can skip automatically inserted characters as long as you
don't explicitly move the text cursor and the editor doesn't lose the
focus. This will be visualized by highlighting the automatically
inserted character as long as you can perform the skipping.

This will reduce unexpected skipping in the case a cursor was explicitly
placed before an closing brace and a closing brace is typed.
