Allow JavaScript components inside of props dict #1319
Description
Current Situation
Libraries like MaterialUI use components within the props dictionary, and this currently isn't supported by ReactPy.
Ref: #989 (comment)
Proposed Actions
We need to spend some additional thought on how to allow JavaScript components to be added as a prop value. This may result in adding some kind of flag that signifies "this prop value is a VdomDict containing a JavaScript child".
