Can someone tell me where this error is coming from? I had these invalid characters in some tags years ago and I thought I fixed all of the references but every once in a while (like every couple of days or even weeks) I’ll see these errors pop up in the console but I can’t figure out what they are from or where those tag references are. They must be buried deep somewhere but I can’t find them. Not causing any other errors or problems other than just being annoying.
