• Broken spaces on docs
• Components events matrix not showing any event
• /assets/gradio.svg broken (used on gradio.live homepage)

It looks like we lost the docs for gr.Group in the migration. (This was previously reported as an issue: #4338)

Nit: the font size for the code in all of the guides is much larger than the surrounding text:

Also it looks like the code blocks don't have copy buttons anymore?
