Approving as this moves things forward to remove the deprecated dependency. We'll want future revisions to figure out what here ought to be further refactored into a reusable vanilla JS library.

Avoid id generally with reusable components, as an application could opt to put multiple components of the same kind on the same page. That being said, no need to change this right now, but it is something to consider when we refactor some of this scanner code into a reusable vanilla (non-framework-specific) JS API.
