Print styles: Wrap CSS-generated URLs
Chrome does not actually break CSS-generated URL content with word-wrap, which
causes some infoboxes to expand to the entire page.
This patch adds the word-break CSS property, which allows Chrome to break
those URLs at any position. This fixes the rendering of infoboxes on pages
like https://en.wikipedia.org/wiki/San_Francisco.
With basically all PDF generators (including browsers) including clickable
links & many PDFs consumed on-screen it might be worth considering making
print URLs optional at some point, and defaulting to "screen optimized" PDFs.
