Bug Description

To give this issue a bit more context - see this discussion:

#1815

Prosemirror seems to strip out font styles from nested text elements by default which causes a loss of text stylings when content is parsed into the editor that is structured like this:

<span style="font-size: 10px;">
  <span style="color: red;">This is red</span>
  <span style="color: blue;">This is blue</span>
</span>

Afaik this would lead to parsed HTML of

<span style="font-size: 10px; color: null;">This is redThis is blue</span>
