title: Webstorm not recognising JavaScript file
body: <p><img src="https://i.stack.imgur.com/wcd0U.png" alt="Look"></p>
  
  <p>Webstorm doesn't recognize one of my .js files as a JavaScript file so I'm losing syntax highlighting and being able to add break points. I've looked in the <code>workspace.xml</code> file and the file in question seems to have similar settings to other .js files that work correctly.</p>
  
  <p>If I change the name of the file it works ok. So somehow Webstorm is stuck on misinterpreting the type of a file that has this name. Where else can I edit the project?</p>
