Event handlers do not infer props correctly

[nasheomirro]

Components have the correct types but are inferring incorrectly:

const Button = polyRef<"button">(
  ({ as: As = "button", ...props }) => {
    return <As {...props} />;
  }
);

// `event` is of type `any` when it should be of type `React.MouseEvent<HTMLButtonElement, MouseEvent>`
<Button onClick={event => {}} />

Note that onClick still has the correct type, it's just that typescript isn't inferring our function. What's weirder is that if you provide an as prop, or explicitly provide a value for the component type, then it will infer correctly.

// both `event`s have the correct type
<Button<"button"> onClick={event => {}} />;
<Button as="button" onClick={event => {}} />;

Looks like this issue is related to how typescript does inference, see accepted answer. I am not sure if there is a solution at the moment.

After some time the trick with commit 03bf3db is now un-needed, I don't know what changed but it has to be some update to typescript or maybe ts-server (idk).
