I cannot see that Safari supports the "connectedCallback" in Custom Elements, which seems to be to be foundational to the entire technology.

If you're correct about Safari's level of support can you referf me to where it supports connectedCallback?

The proof, as they say, is in the pudding: https://codepen.io/WickyNilliams/pen/dydoNez

It's been supported for years AFAIK. As long as you extend HTMLElement, and not some other element, everything will work as expected
