Webkit Regression is causing :checked selection to fail

[atomicpages]

See details here regarding the blink/webkit regression: https://bugs.chromium.org/p/chromium/issues/detail?id=1006586#c1

For pretty-checkbox-react I'm working on a re-write using hooks and I noticed the indeterminate checkbox is failing since I rely on state to update the DOM rather than CSS. I think we need to add an :indeterminate selection for fonts, svgs, and images
