Line breaks in html_notes

Hi everyone.

I am gonna post a lot of information in the description of a task.
This needs to be formatted a little. I can’t get Line-breaks to work. From what I have read so far the
tag or \n does not work. Is there really no way of getting a line break?

I do get line-break by making my code like this:

$faceSummary = '<b>Facebook</b>
                            <b>Formater:</b>
                            ' . $fimagead . '
                            ' . $fvideoad . '
                            ' . $fcarousel . '
                            ' . $flightimage . '
                            ' . $fcollection . '
                            ' . $face_spending . '
                            
                            ' . $face_techfee . '
                            ' . $f_customer_spending . '
                            ' . $f_date_from . '
                            ' . $f_date_to . '';

But then the formating will look like this:
