When deploying the new print styles, I noticed that the logo was not showing.
When deploying there was a spike in errors:

The index notices have been fixed, but it looks like there are some other errors we will need to investigate:

During deployment we saw:
```

To help debug the change I had the styles instead deployed to test wiki:
https://test.wikipedia.org/wiki/Planet
The CSS file shows that the CSS relating to the pseudo element is not applying.
https://test.wikipedia.org/w/load.php?modules=skins.vector.styles.experimental.print&only=styles&debug=true
This should only happen when VectorPrintLogo is not defined.
During deployment however, I saw thisThe background image of the pseudo element butt at the top of the background page resolves to "url(data:image was a blank SVG./svg+xml;base64,)"
