textarea newline not showing in markdown

[thexs-dev]

I have this simple combination:

   <paper-textarea value="{{content}}"></paper-textarea>
   <marked-element markdown="{{content}}">

However, a newline in textarea won't show up in marked-element as I expected, unless it's followed by a space or there are two newlines
Is that an issue in either element or the expected behavior?
Thanks, Fausto
p.s. MD from this GitHub comments page works as I'd expected

To allow for GFM line breaks, so there's no need to use MD's two-space line breaks, I just included the following line of code within a script tag

window.marked.options({breaks:true}); // to enable GFM single line break
