Thank you for making this extension! I've had to disable it and just use it on-demand until this is resolved, thank you! 🙏

Thanks @meadowsjared. I haven't updated the internals in many years, actually surprised it works at all! I have wanted to rewrite it but I have not had time. I'll update this report when I'm able to.
