For historical reasons, st.text/markdown/json/alert all share the same proto (Text) and they're all handled by the same element Text.tsx). This makes no sense, though. We should split them out.

Many people on constrained data plans turn on data saving — their smartphone browsers then send a "Save-Data" header to servers.
