<kbd> and new line in HTML list

[machal]

Hi,

I've problems with parsing this string:

1. **TEST**   
<kbd>Ctrl/Cmd+Z</kbd> lorem [video](http://devtoolstips.com/). 

As you can see on screenshot from http://parsedown.org/demo, original Markdown parses it correctly:

Looks like I found a similar issue:

# Shortcuts

## Header 1

<kbd>⎋</kbd>  Escape

## Header 2

We should be following CommonMark in this area now, changes will be in the next release :)
