Marked adds extra/unnecessary <p> tags to list elements

[utdrmac]

Describe the bug
When using lists with linebreak separation, Marked adds unnecessary <p> tags to list items.

To Reproduce
Using CommonMark, the following adds erroneous <p> tags around the BBB, DDD, and EEE elements.
Using MarkedDemo, the following adds <p> tags around AAA (correct) and BBB (incorrect).

## Testing

* AAA

* BBB
    * CCC
* DDD
* EEE

Expected behavior
With the above code, only AAA should have <p> element wrappers.

** Additional Example **

## Testing

* AAA
* BBB
    * CCC
* DDD

* EEE

Above, CommonMark adds around AAA, BBB, DDD, EEE.
Above, MarkedDemo adds around DDD, and EEE

Why is it incorrect to add <p> tags around BBB, DDD, and EEE? Is this in the spec somewhere?

Because that doesn't make any sense. I put a new line between AAA and BBB, so why are other list items being affect by this?

[utdrmac]

Similar situation: commonmark
There's a line break before EEE, so why are other elements also getting p tags? If you remove this line break, all p tags disappear. It is inconsistent behavior.

[UziTech]

according to the spec:

A list is loose if any of its constituent list items are separated by blank lines

... paragraphs in a loose list are wrapped in <p> tags, while paragraphs in a tight list are not.

So CommonMark seems to do it correctly.

Marked should include <p> tags on all first level list items in the demo.

That's very odd. I'd like to see a real-world use case where having a line break on the last element of a list should affect every element that comes before or after it, instead of just affecting 'it'.
