Lists not being joined on toggleList

[YousefED]

When you use toggleList, the new list is not joined with lists above / below.

Bug demonstration:

I'd expect it to behave similar to when I type the "- " shortcut to create a list:

The WrappingInputRule takes this scenario into account (https://github.com/ProseMirror/prosemirror-inputrules/blob/master/src/rulebuilders.js), but toggleList does not.

I think this should happen automatically (join with lists above / below), or be an option for the toggleList command.

Ah yeah that makes sense!

Related; ProseMirror WrappingInputRule actually only joins with items above. I think it might also make sense to join with items below (when typing "-" above an existing list). Let me know if you'd like me to open a separate issue for this
