title: IntelliJ is not formatting HTML
body: <p>Have been using IntelliJ for years, and been happy and hope this is a fluke. 
  IntelliJ is not formatting HTML code when I do Ctrl-Alt-L. The dialog pops, and it pretends to format, but no code is actually moved. I switched extension of the file from HTML to XML, and formatting worked as expected. Actually I noticed this in Freemarker templates, but then experimented with pure HTML with the same results. 
  My version is 13.0.2</p>
  
  <p>Any help is appreciated. </p>
