Transform selection into a stand-alone new editor state

[mariusplanable]

Hola amigos,

Trying to achieve the following:
Having a selection in the editor (which may stretch across different types of nodes) to extract somehow the selected nodes and instantiate a new editor from them. Imagine you want to select a part of editor content and suggest a change to it, so after selection a new floating editor would pop up with the selection as the initial state.

What I'm currently doing (which is working OKish for plain text, but not really for rich text) is trying to create a serialized editor state (something editor.getEditorState().toJSON() would return) by traversing selection.getNodes() and trimming the anchor/focus nodes to the selection offsets. Then, this serialized editor state would be provided to the new editor. There a multiple use-cases to handle with such an approach, like for example selecting part of a ListNode only, or having the selection starting into a MarkNode.

I am wondering if there is an easier way to create a standalone editor state from a selection.

Thanks in advance for any input which will be much appreciated.
