Description
module A = {
[@react.component]
let make = () => {
<>
<a/><a/>
</>;
}
}
This code gives a syntax error on line 5 - <a/><a/>. If you add whitespace between those elements, it fixes it. I'm seeing other issues similar to this, but they are closed, so I'm not sure if this is just a problem with an older version in the playground.

Research direction
Reproduce the example in the linked Reason playground, first with adjacent self-closing elements and then with whitespace between them. Trace the JSX parsing entry point responsible for the syntax error; done means the shown JSX is accepted without requiring whitespace between the two elements.
