slate-lists breaks default formatting behaviour when creating new list

[asiraky]

It appears that the slate-lists package is breaking default slate behaviour.

1. create a numbered or bullet list item
2. set the cursor selection to bold (or any other styling)
3. type some bold text
4. press enter
5. type something

The second list item wont be bold. This breaks the (very useful) default behaviour of slate, which is to bring across the formatting to the new list item.

EDIT: I noticed this broken behaviour is also present in the production Prezly app.
