* @summary Remove selection marker with optional `<p>` parent.
* @summary Remove selection marker and the parent node if it is an empty paragraph.
*
* By default TinyMCE puts every inline node at the main level in a `<p>` wrapping tag.
* By default TinyMCE wraps loose inline tags in a `<p>`.
* When removing selection markers an empty `<p>` may be left behind, remove it.
*
* In the case with selection markers, when removed they leave an empty `<p>` behind,
* which adds an empty paragraph line with `&nbsp;` when switched to Text mode.
*
* In order to prevent that the wrapping `<p>` needs to be removed when removing the
* selection marker.
*
* @param {object} editor The TinyMCE Editor instance
* @param {object} marker The marker to be removed from the editor DOM
* @param {object} $marker The marker to be removed from the editor DOM, wrapped in an instnce of `editor.$`
