Subject: [PATCH] [FIX] web: no ResizeObserver video error on chrome

When displaying a video, with the browser window at a certain size, or
resizing it (or opening developer tools) we could the following error:

 "ResizeObserver loop limit exceeded"

This can be reproduced in chromium just with this JS code:

  window.onerror = function(e){ console.log(e); };
  document.body.innerHTML = '<div><video controls src="v.webm"/>';

The issue only happen if:

- the video server does not support HTTP range requests
- the controls are displayed on the video
- browser size is in problematic size/resized to problematic size

And the error is raised in window.onerror but not displayed in the
developer console.

With this change, we ignore these errors until fixed in chromium.
