Incorrect handling of initial or pasted nested lists

[cutteroid]

At the moment editor cant handle nested lists

1. Visit playground

2. Paste this in html tab

    <div id="editor-container">
           <ol>
               <li>one</li>
               <li>
                   <b>two</b>
                   <ul>
                       <li>unordered</li>
                       <li>unordered</li>
                   </ul>
               </li>
               <li>three</li>
           </ol>
       </div>

3. Notice incorrect list structure in editors tab

Similar to the mentioned issue, I guess I come across a scenario that can’t be expressed as a Delta object where line breaks are used to specify block elements/styles:

         <ol>
            <li>one</li>
            <li>
                <b>two</b>
                <ul>
                    <li>unordered</li>
                    <li>unordered</li>
                </ul>
                <b>still two</b>
            </li>
            <li>three</li>
        </ol>

As you can see there is another text after the nested lists ends which still belongs to the second list item.

There is the remaining issue of the numbering being incorrect in the example but there is another issue #829 regarding this specifically
