Clare Ming b24cf900fe Force legacy TOC to render at lower resolutions
- If TOC A/B test is enabled, page is in treatment group, and
viewport is below tablet, force legacy TOC to render.
- If TOC A/B test is disabled and new TOC feature is enabled,
and viewport is below tablet, neither TOC should render.
