'BlankLine' object has no attribute 'children' when parsing a text with gfm

[Emre Sülün]

I am not sure if this is the expected behaviour.

from marko.ext.gfm import gfm
text = '## The problem\r\n\r\nwhenever we are launching the website. The site asks for permission to send notifications but unfortunately, we are unable to handle it.

gfm(text)

Error: AttributeError: 'BlankLine' object has no attribute 'children'

A BlankLine shouldn't have children I guess, but gfm parser tries to parse its children.

Can you show a bit more tracebacks?
