Pagesense snippet required updating

Hi,

My pagesense snippet.js is flagging a warning in:

Browser console logging
PageSpeed Insights test

Error message as follows:

DOM Mutation Events, including `DOMSubtreeModified`, `DOMNodeInserted`, `DOMNodeRemoved`, `DOMNodeRemovedFromDocument`, `DOMNodeInsertedIntoDocument`, and `DOMCharacterDataModified` are deprecated (https://w3c.github.io/uievents/#legacy-event-types) and will be removed. Please use `MutationObserver` instead.

Use of Mutation Events is deprecated. Use MutationObserver instead.

Can you please advise if I need to do anything from my end?

CSS not loading in heat map view
I ran into a problem with two different websites where when I view the heat map experiment, the CSS for the page is not loaded under the heat map overlay. When going to the page directly, everything looks fine. The page also looks right on the Experiments page where a screenshot is used as the thumbnail... The sites are both WordPress websites. I've tried both the regular snippet and async. I'm hoping this has been seen before and there's a solution. Thanks!
