jsx output incorrect for text between tags on same line

buble doesn't handle inline jsx text correctly:

$ cat test.jsx 

ReactDOM.render(
  <Foo> <h1>Hello {name}!</h1>   </Foo>,
  document.querySelector( 'main' )
);

Correct:

$ cat test.jsx | babel
'use strict';

ReactDOM.render(React.createElement(
  Foo,
  null,
  ' ',
  React.createElement(
    'h1',
    null,
    'Hello ',
    name,
    '!'
  ),
  '   '
), document.querySelector('main'));

Incorrect:

$ node_modules/.bin/buble -v
Bublé version 0.10.6

$ cat test.jsx | node_modules/.bin/buble 
ReactDOM.render(
  React.createElement( Foo, null,  React.createElement( 'h1', null, "Hello ", name, "!" )    ),
  document.querySelector( 'main' )
);

Notice how the input source is treated differently by babel if each tag is on its own line:

$ cat test2.jsx 
ReactDOM.render(
  <Foo>
     <h1>Hello {name}!</h1>
  </Foo>,
  document.querySelector( 'main' )
);

$ cat test2.jsx | babel
'use strict';

ReactDOM.render(React.createElement(
  Foo,
  null,
  React.createElement(
    'h1',
    null,
    'Hello ',
    name,
    '!'
  )
), document.querySelector('main'));

I think only leading whitespace and trailing whitespace can be elided in JSX, not whitespace between tags on the same line.

Edit - babel version used:

$ babel -V
5.8.29 (babel-core 5.8.38)
