print view doesn't consistently include background logo

Using 4725350 and

data-background-image="some.png"
data-background-position="bottom left"
data-background-size="15%"

and creating the slides using a single markdown document the export to pdf only has the logo on the last slide for me. In the presentation the logo is (as expected) on every slide. I think if no vertical slides are present the logo is present.
