[lit-html][Edge 18] typeof super.attributeChangedCallback === 'function' while it is undefined

Suspected Root Cause:

Edge cannot properly access properties of super pseudo-object
This is an Edge issue.

Workaround as a fix:

Simple super.attributeChangedCallback to check if it is truthy, instead of checking typeof

Note

This workaround fix also fixes the hang-up issue on Edge 17
