Editing for nested quotes and lists

[jeromesimeon]

Is your feature request related to a problem? Please describe.
Markdown can support nested quotes and lists. Those seem to be properly imported in the editor, but one cannot edit those or create them directly using the toolbar.

Describe the solution you'd like
It would be nice to be able to create a quote containing a list or a list containing a quote, or a quote containing a list containing a quote. This might require some thinking about the scope for the toolbar buttons.

Currently one can load the following markdown:

Clicking on the 'list' button for the paragraph does two things: remove the quote and add the list. Should it just add the list without removing the quote?

Can I take this up? I had achieved this functionality with the keyboard shortcuts, but discarded because I thought it is not an ideal behavior.
