title: Opening Devtools on Chrome makes entire page trip
body: <p>I'm working on a small website and I'm writing a website almost from scratch. I'm using Bootstrap 4 and I'm modifying only basic CSS.</p>
  
  <p>Whenever I open the Chrome Devtools, the website completely flips out and it looks like it keeps reloading. The entire website only loads from localhost, however, the network tab keeps showing repeating requests to the saem assets, over and over again. The second I quit Devtools, the entire behavior stops. I've tried installing a cache killer, tried incognito, but the problems keeps appearing.</p>
  
  <p>I'm also using Octicons, and what I have noticed is that when I manage to get the Devtools to at least stay focussed at the right part, the <code>&lt;i class="oi oi-chevron-right"&gt;</code> node keeps flashing in purple, indicating there is a change to that node. I can't open it and even just clicking on it won't help, the entire CSS keeps shifting in the inspector bar and it seems like something is making rapid changes. It appears that Chrome re-applies styling changes that I made a few days back, such as locally modifying the margin of an element.</p>
  
  <p>I was able to work on the website just fine a few days ago, but even moving back in commits won't keep the problem from happening. I am starting to think it is a bug with Chrome, but I can not confirm this in any way.</p>
  
  <p>Is there anything that is known to break Chrome's Devtools, that might explain this behavior, or is there a way to clear the cache of the Chrome Devtools specifically?</p>
  
  <p>The "Changes" tab in Devtools reports that there are no changes, but the CSS I see on page makes me seriously doubt it. Removing the icons entirely does not seem to resolve the problem, so I think the issue lies elsewhere. Breakpoints are not triggered either.</p>
