[Feedback] Preserve JSX mode

Sorry, I don’t know how I can set the necessary compiler flags in the playground.

But I just tried to build a simplified example and something strange happend.

I have this simple component:

@jsx.component
let make = () => {
 <div className="text"></div>
}

When using these settings in my rescript.json:

{
  "bsc-flags": [ "-bs-jsx-preserve" ],
  "jsx": {
    "version": 4,
    "module": "MyOwnJsx"
  }
}

it actually works and the component gets compiled as expected.

function Btn(props) {
  return <div className={"text"}/>;
}

But when I change the code in my MyOwnJsx.res:

module Elements = {
  type props = JsxDOM.domProps

  @module("myownjsx")
  external jsx: (string, props) => Jsx.element = "jsx"

and remove the @module("myownjsx") part:

module Elements = {
  type props = JsxDOM.domProps

  external jsx: (string, props) => Jsx.element = "jsx"

the code will be compiled to:

function Btn(props) {
  return jsx("div", {
    className: "text"
  });
}

So I think the solution would be to simply provide the dummy @module entry. But the bahaviour was a bit surprising for me.
