[VS2013/2015] Wrong formatting in jsx expressions in attributes of jsx elements

[vladima]

import * as React from "react";
<div
    autoComplete={(function () {
        return true/*1*/
    })() }
    >
</div>

Type ';' at /*1*/

Probably lo-pri but it will be nice to not to have such glitches

fixed in #4398, regression tests is added in #6348
