title: "ResizeObserver - loop limit exceeded" | API is never used
body: <p>I am running a hybrid PhoneGap app (for a several years, running Cordova Android 6.1.2, more recently 9.0); for years, our #1 javascript error by a <em>significant</em> margin has been</p>
  <pre><code>ResizeObserver loop limit exceeded
  </code></pre>
  <p><em><strong>However</strong></em>, the key distinction for my issue compared to the many other reports found on Google of this error is is that there are 0 instances of ResizeObserver being used anywhere in my code. Searching my entire computer, the only instance of ResizeObserver showing up <em>anywhere</em> is a random Steam file. Looking at my app while it's running, setting <code>window.ResizeObserver = undefined</code> doesn't break/do anything and <code>document.resizeObservers</code> (per the W3C documentation) returns nothing.</p>
  <p>I have seen this post, which seems to be the canonical one for this error: <a href="https://stackoverflow.com/questions/49384120/resizeobserver-loop-limit-exceeded">ResizeObserver - loop limit exceeded</a> . The answer of &quot;This error means that ResizeObserver was not able to deliver all observations within a single animation frame. It is benign (your site will not break).&quot; would be sufficient for me if I was actually using ResizeObserver. Since I am not using it, I am concerned that this error showing up is indicative of something larger going wrong.</p>
  <p>There is no discernible pattern from our users' Chrome version/locale/time zone/Android version/etc/etc, unfortunately.</p>
  <p>I've researched this API extensively and have found nothing that would indicate to my issue; either why there would be some sort of phantom ResizeObserver running and/or why that error would show up in an app that doesn't use that API.</p>
  <p>Any help here (even just a vague direction to look at) would be very much appreciated. Thanks so much!</p>
