I was working another issue with regard to rendering issues after a recent Chromium browser update and came across some interesting errors in the browser dev console.

This only seems to occur on the tech login on the dashboard page. The top error 'DOMNodeInserted' occurs elsewhere and I think this has been around for some time. The rest of them I've not noticed before. I've checked for this in 12.8.4 and 12.8.5 in multiple environments and multiple browsers and the errors are present in all.
Curious to see if this is seen elsewhere.
