typeof Flow return type breaks syntax highlighting

[awilliams-atx]

Here's the snippet that produces this syntax highlighting break:

class FooClass {
  fooMethod(): typeof FooEnum {
    return {};
  }
}

A screenshot of the syntax highlighting breaking:

I have ensured that my vim-javascript and vim-jsx are up to date.

I have disabled all other plugins besides vim-javascript and vim-jsx and the problem does persist.

My workaround:

class FooClass {
  fooMethod(): {|...typeof FooEnum|} {
    return {};
  }
}
