Summary: React 16 is not compatible with react-emotion 9 (it prints warnings, see also https://github.com/emotion-js/emotion/issues/644). So we should upgrade to 10.

Summary:
Currently most components are shown anonymously in the component tree, because using `styled` creates unnamed components, shown as the HTML elements they result in.
This has two downsides:
1. React errors / warnings are really vague and it is hard to locate where they are coming from
2. The React Devtools don't show which components are rendering.
3. The effect of the latter it is hard to copy-from-example when developing plugins. This leads to a lot of inconsitency and duplication in the layouts of components
