/**
 * Apparently EditText blocks touch event propagation to the parent even
 * when disabled/not clickable/not focusable. Therefore we have to manually
 * check whether we are enabled and either ignore the event or process it normally. <br/>
 * <br/>
 * This class also blocks the default EditText behaviour of textMultiLine flag enforcing replacement
 * of the IME action button with the new line character. This allows rendering soft wraps on single
 * line input.
