Class with static initialization block highlighting issue

[blmatthews]

class Test
{
    static
    {
        console.log('here');
    }
} // This is highlighted as an error. Removing the } on the previous line "fixes" it.

I tried a .vimrc that only does syntax enable and includes this plugin. I also tried various colorschemes. Neither made a difference. Wrapping it in some HTML as shown in the image below lets a browser load it without complaint and execute the console.log('here') (the console.log is there only to show the browser thinks it’s valid HTML and Javascript, the closing } is highlighted as an error even without the console.log line).
