In order to separate the SVG content from the rest of the engine, it gets its very own Page, PageClient, top-level browsing context, etc. Unfortunately, we do have to get the palette and CSS/device pixel ratios from the host Page for now, maybe that's something we could refactor in the future. Note that this doesn't work visually yet, since we don't calculate the intrinsic sizes & ratio for SVG images. That comes next. :^)
