title: ResizeObserver - loop limit exceeded
body: <p>About two months ago we started using Rollbar to notify us of various errors in our Web App. Ever since then we have been getting the occasional error:</p>
  
  <p><code>ResizeObserver loop limit exceeded</code></p>
  
  <p>The thing that confuses me about this is that we are not using <code>ResizeObserver</code> and I have investigated the only plugin which I thought could possibly be the culprit, namely:</p>
  
  <p><a href="https://www.npmjs.com/package/aurelia-resize" rel="noreferrer">Aurelia Resize</a></p>
  
  <p>But it doesn't appear to be using <code>ResizeObserver</code> either.</p>
  
  <p>What is also confusing is that these error messages have been occuring since January but <code>ResizeObserver</code> support has only recently been added to Chrome 65.</p>
  
  <p>The browser versions that have been giving us this error are:</p>
  
  <ul>
  <li>Chrome: 63.0.3239 (ResizeObserver loop limit exceeded)</li>
  <li>Chrome: 64.0.3282 (ResizeObserver loop limit exceeded)</li>
  <li>Edge: 14.14393 (SecurityError)</li>
  <li>Edge: 15.15063 (SecurityError)</li>
  </ul>
  
  <p>So I was wondering if this could possibly be a browser bug? Or perhaps an error that actually has nothing to do with <code>ResizeObserver</code>?</p>
