Fail when JSX.IntrinsicElements is an intersection type

[Knagis]

TypeScript Version: 2.1.4, 2.2.1, 3.6.3, 4.0.3

The compiler does not support JSX.IntrinsicElements that are intersections. It even fails with an exception instead of an error message.

The reason why I think I require this behavior is that I want the IntrinsicElements to be something like:
{ [P in keyof HTMLElementTagNameMap]: Partial<HTMLElementTagNameMap[P]> } & { [P: string]: Partial<HTMLElement> }

Code

intrinsic.jsx.d.ts

declare namespace JSX {
    // change the alias to use the different versions
    type IntrinsicElements = IntrinsicElements4;

    // works
    type IntrinsicElements1 = {
        a: Partial<HTMLAnchorElement>;
    }

    // works
    type IntrinsicElements2 = {
        [P: string]: Partial<HTMLElement>;
    }

    // works
    type IntrinsicElements3 = {
        a: Partial<HTMLAnchorElement>;
        [P: string]: Partial<HTMLElement>;
    }

    // does not work
    type IntrinsicElements4 = IntrinsicElements1 & IntrinsicElements2;

}

intrinsic.tsx

/// <reference path="intrinsic.jsx.d.ts" />
function jsxCreate() {}

let a = <a href="about:blank">foo</a>;
let b = <foo>bar</foo>;

tsconfig.json

{
    "compilerOptions": {
        "jsx": "react",
        "jsxFactory": "jsxCreate"
    },
    "files": ["intrinsic.tsx"]
}

Expected behavior:

IntrinsicElements4 variation should work the same as IntrinsicElements3 which is semantically the same.

Actual behavior:

The code does not compile, the compiler fails with an exception:

Is there any update on this issue?

[Knagis]

This issue is still present in 2.2.1 - the compiler still crashes with an unhandled exception.

[Knagis]

This is still actual in 3.6.3.

[Knagis]

Still actual in 4.0.3 though the message changed a bit

Cannot read property 'flags' of undefined

Full stack on 4.0.3

Compiler no longer crashes on this example, starting from version 4.3. Seems the issue has been fixed.
