Currently, selecting a block of text, then applying list formatting (either ordered or unordered) replaces the text with an empty list. Starting a list, then pasting text, puts all of the text under the current entry in the list.

Ideally, it would apply the list formatting to existing text based on line breaks, and respect line breaks in pasted text to extend an existing list.

On iOS, not sure if this applies on android/web app.
