KO without empty line

SUMMARY
Markdown back-end in Okular does not render a table, if the source MD has a line of text (instead of an empty one) before the line containing the table header.

STEPS TO REPRODUCE
Use the following source:

This is a table:
IP dest.	| Service			| Port ext	| Port int
:---		| :---: 			| ---:		| ---:
192.168.0.2	| homer				| 9010		| 8080

OBSERVED RESULT
Table does not render. Table DOES render if you add an empty line after "This is a table:".

EXPECTED RESULT
Table should render in any case, no matter if an empty line or a line of text comes before it. At least, that's what an MD web renderer does:

SOFTWARE/OS VERSIONS
0.1.0 version of the MD backend

This is how our backend (discount) works. Cf. "discount-mkd2html test.md" with and without the newline.

You can report issues in the discount renderer here:

Thanks for understanding.
