When a lighthouse from Google (https://pagespeed.web.dev) checks a site on joomla 4 with installed Gantry5, a warning is issued about an outdated API

Deprecated APIs will eventually be removed from the browser.

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.

This API is located in /media/gantry5/assets/js/main.js

Is it possible for the developers of gantry 5 to fix this warning?

You didn't mention the CMS you are using, but in reviewing this, it appears to be a duplicate of #3174 which involves the Grav CMS.

Why didn't I mention CMS?

My apologies, you're correct. I didn't get much sleep last night so I obviously just ended up glazing over that.

It still stands though, the issue you are facing seems to be the same as in the other ticket. It must have something to do with the Libraries that Gantry 5 is using which is cross platform compatible and independent of the CMS and Themes.

@hexplor Can you take a look at this?

if the developers are aware of this problem, then I will close my ticket.
I will look forward to when the problems are fixed and I can update all my sites with the new version of gentry.
Thank you!
