Using face of newline for remainer of display line

[Jonas Bernoulli]

Is it possible to use all properties of the face of the newline
character at the end of a line for the complete remainer of the display
line?

  (insert (propertize "heading\n"
                      'face '(:background "gray90" :underline t)))

This causes the complete display line to use "gray90" as background
color, but only "heading " is underlined.  Is there a way to tell Emacs
to also use other face properties for the remainer of the display line?

  Thanks,
  Jonas
