126 * Mainly used to put emoji in already generated DOM
127 * without compromising surrounding nodes and
128 * **avoiding** the usage of `innerHTML`.

149 * is anyhow meaningful.
150 * By default this is ignored.

153 * of a valid `src` to use for the image, nothing will
154 * actually change for that specific emoji.
