JSX attribute completions sometimes don't work when tag type arguments are specified

[jakebailey]

In the below example, completing after GenericElement<number> in f1 doesn't work (no xyz), but in f2, it does. Note that this is not new and is unrelated to snippets (so my other PRs for JSX snippets don't change anything, we just found it in testing).

declare const React: any;

namespace JSX {
    export interface IntrinsicElements {
        div: any;
    }
}

function GenericElement<T>(props: {xyz: T}) {
    return <></>
}

function fn1() {
    return <div>
        <GenericElement<number> />
    </div>
}

function fn2() {
    return <>
        <GenericElement<number> />
    </>
}
