Erroneous paragraphs inserted into list items when specifying two consecutive lists

[joepie91]

When specifying the following Markdown (without any non-default options specified for marked):

* BTC - Bitcoin (Blockchain.info)
* USD - United States Dollar (ECB, via fixer.io)
* CAD - Canadian Dollar (ECB, via fixer.io)
* GBP - British Pound (ECB, via fixer.io)
* CNY - Chinese Yuan (ECB, via fixer.io)
* RUB - Russian Ruble (ECB, via fixer.io)
* JPY - Japanese Yen (ECB, via fixer.io)
* AUD - Australian Dollar (ECB, via fixer.io)
* NZD - New Zealand Dollar (ECB, via fixer.io)

* BGN - Bulgarian Lev (ECB, via fixer.io)
* BRL - Brazilian Real (ECB, via fixer.io)
* CHF - Swiss Franc (ECB, via fixer.io)
* CZK - Czech Koruna (ECB, via fixer.io)
* DKK - Danish Krone (ECB, via fixer.io)

* INR - Indian Rupee (ECB, via fixer.io)
* KRW - South Korean Won (ECB, via fixer.io)

... this is the result (beautified, tested via an instance in the browser):

Despite being syntactically valid - two separate lists, delimited by two newlines like any other 'element' in Markdown - strange paragraphs are inserted at the 'intersection' of the two; that is, the last element of the first paragraph, and the first element of the last paragraph.

Options for correct (that is, sensible and expected) behaviour would include:

• Producing two separate <ul> elements, without any paragraphs in the list items.
• Producing one combined <ul> element, effectively ignoring the double-newline, without any paragraphs in the list items.

GitHub itself appears to be having the same issue, but I'm not sure whether they use marked or a port of it (or even just an implementation based on the same rules). I've reported the issue to them separately.

@joepie91: Does the smartLists option yield the same result?

[joepie91]

Yes, it seems to behave the same regardless of the smartLists setting.

You should put two empty lines (aka 3 newlines) in between the two blocks to get two separate lists with marked:

Github doesn't use marked, nor a port of it.
