Codesandbox Case (Bug Reports)

Current behavior
The imperative Message API accepts custom markup for summary/detail, but if you use Message inline:

<Message severity="error" text="Field is required">

, then you only get the text property which is documented and typed as a string, not e.g. ReactNode (ts).
Message also doesn't render children.
In practice you can shove nodes into text:

<Message severity="error"
	//@ts-ignore
	text={<span>Test</span>} />

, and it works, but it should be a documented feature.

Expected behavior
Message should accept custom node content in some way, e.g. as children:

<Message severity="error"><span>Test</span></Message>

The 'content' property can be a string, function(props) or JSX element.
