title: IntelliJ SASS file watcher doesn't detect changes in SCSS file
body: <p>I have a <code>style.sass</code> file that <code>@use</code>s several <code>_*.sass</code> partials. That was all working fine. Now I added a <code>_*.scss</code> file (it just contains a map, so I wanted it to be multiline), but editing that file does not trigger a rebuild of the <code>style.sass</code> file. I tried adding a SCSS file watcher too, since I'm not sure how IntelliJ decides what to watch, but that didn't help.</p>
  <p>It works fine using Dart-SASS's <code>--watch</code> argument. How do I make IntelliJ do the same?</p>
  <p>(Although it's a Play project, I'm using IntelliJ's file watchers because I wanted to be able to use <code>@use</code>, so I needed Dart SASS.)</p>
