title: min.js.map files not found, console logs. Getting unexpected CSS behaviour
body: <p>I'm getting the following logs in my console </p>
  
  <pre><code>[2020-01-30 16:34:40] ERROR `/vue.min.js.map' not found.
  [2020-01-30 16:34:40] ERROR `/raven.min.js.map' not found.
  [2020-01-30 16:34:40] ERROR `/popper.min.js.map' not found.
  </code></pre>
  
  <p>I do not how to interpret this logs, definitely haven't found those files in my file system.
  Should I have them? What are they for? How to fix this issue?</p>
  
  <p>I suspect that this error has something to do with some weird CSS behavior when building the project and working locally.</p>
