spread jsx generic overload

🕗 Version & Regression Information

💻 Code

function GenericComponent<T>(props: { foo?: string }) {
    return null
}
function GenericComponent<T>(props: { foo?: string }) {
    return null
}
<GenericComponent {...omit(['foo'], otherProps)} />;

🙁 Actual behavior

Spread types may only be created from object types.(2698)
unless we save omit(['foo'], otherProps) in an intermediate variable and spread that instead (work around in playground).

🙂 Expected behavior

No error since it's valid at runtime. It's also accepted by TS without JSX or on non-generic components or if we save the value in an intermediate variable. All cases are explored in the playground.

#51580 and #52837 didn't play along, so the fix for this has been reverted.
