IntelliJ - Tab indentation in Javascript does not work
<p>I want to use tabs for indentation in my Javascript files. I changed the configuration as usual, but the preview doesn't seem to take my modification in account. Neither in the acutal files.</p>

<p>What is surprising is that the "Spaces" subtab is formatting the code the right way, but it's is the only place where it works. (See screenshots below)</p>

<p>Did anyone have the same issue ?</p>

<p>I am using IntelliJ Ultimate 2016.1</p>
