Highlighting broken when a class lambda returns a single JSX tag not enclosed in parentheses

[naveg]

See mxw/vim-jsx#148 - this is some discussion of this being an issue with vim-javascript, not vim-jsx

const MyFunctionalComponent = () =>
  <div className="MyFunctionalComponent">
    My highlighting also works!
  </div>


                
class MyComponent extends React.Component {
  render = () =>
    <div className="MyComponent">
      My highlighting is broken
    </div>
}

class MyParensComponent extends React.Component {
  render = () => (
    <div className="MyParensComponent">
      My highlighting works!
    </div>
  )
}

Here's a modified plugin section of my vimrc. The bug reproduces with a vimrc consisting of this snippet only.

if empty(glob('~/.vim/autoload/plug.vim'))
  silent !curl -fLo ~/.vim/autoload/plug.vim --create-dirs
    \ https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim
  autocmd VimEnter * PlugInstall | source $MYVIMRC
endif

call plug#begin('~/.vim/plugged')

Plug 'pangloss/vim-javascript', {'for': ['javascript', 'javascript.jsx']}
Plug 'mxw/vim-jsx', {'for': ['javascript', 'javascript.jsx']}

call plug#end()

babel/babylon#540 (comment) hopefully this will solve the problem
