Link attributes in Markdown not working

can’t figure out what’s wrong with my page. It doesn’t process the nofollow attribute.
For the sake of example I do have the following link in MD:

[Google Fonts](
and it’s rendered without the attribute:

process: markdown: true
doesn’t make any difference

On the other hand I have another page with the form. I’ve inserted the class inside the link of a label. To make it work I had to append the form element with markdown: true option.

        name: checkName
        classes: 'extra-class'			
        label: 'text [more](/more?classes=some-class)'
        type: checkbox
        markdown: true			

So, inside the form, the attribute does work, while on the first page there is a problem.
