			 * Inspired by:
			 * @link https://stackoverflow.com/a/17497803/153310
			 *
			 * Why do it this way and not with TinyMCE's bookmarks?
			 *
			 * TinyMCE's bookmarks are very nice when working with selections and positions, BUT
			 * there is no way to determine the precise position of the bookmark when switching modes, since
			 * TinyMCE does some serialization of the content, to fix things like shortcodes, run plugins, prettify
			 * HTML code and so on. In this process, the bookmark markup gets lost.
			 *
			 * If we decide to hook right after the bookmark is added, we can see where the bookmark is in the raw HTML
			 * in TinyMCE. Unfortunately this state is before the serialization, so any visual markup in the content will
			 * throw off the positioning.
			 *
			 * To avoid this, we insert two custom `span`s that will serve as the markers at the beginning and end of the
			 * selection.
			 *
			 * Why not use TinyMCE's selection API or the DOM API to wrap the contents? Because if we do that, this creates
			 * a new node, which is inserted in the dom. Now this will be fine, if we worked with fixed selections to
			 * full nodes. Unfortunately in our case, the user can select whatever they like, which means that the
			 * selection may start in the middle of one node and end in the middle of a completely different one. If we
			 * wrap the selection in another node, this will create artifacts in the content.
			 *
			 * Using the method below, we insert the custom `span` nodes at the start and at the end of the selection.
			 * This helps us not break the content and also gives us the option to work with multi-node selections without
			 * breaking the markup.
