That seems to be just the background for ads shown by the website.
It seems to rotate them at every 30 seconds and they sometimes have issues loading.

Well, on the OnePlus device, these commercials aren't loading at all on RC build.

I think this is mostly the site's fault because it happens on my Chrome 91 on Samsung Galaxy A20s (Android 10) and Samsung Galaxy J2 Prime (Android 6.0.1) too.

Also look at the list of https://travelandleisure.com trackers that cannot work together perfectly and can cause various errors.
