Line Break with Less Than Symbol Gives Incorrect Syntax Highlighting

TS and JS Grammar Extension version: 0.0.18 / latest

From: microsoft/vscode#22951

Code

For TypeScript code:

export class SomeClass {
    private someMethod(): void {
        if (1
            < 2) {
            console.log("TypeScript syntax highlighting is broken!");
        }
        else if (1 > 2) {
            console.log("");
        }
    }

    private someOtherMethod() {
        console.log("");
        //
        const q = 1;
        var s = 2;
        let e = 3;
    }

    q = 100;
}

When using JavaScript syntax highlighting instead, things are correct as with the typescriptreact language. I suspect the issue is with the <*> style type casts
