Fix print @page only external resource loading
Even though UpdateStyleAndLayout is called after setting media type
to print, not all print only resources loadings are initiated.
Calling also StyleForPage() triggers the remaining ones, like for
@page only background images, via state.LoadPendingResources().
There may be additional edge cases that may need to be revisited
later, like loading that is triggered only with certain page sizes,
due to container queries, for instance.
