Prevent incorrect usage of `tracking_attrs` helper
tracking_attrs
can silently override or be overridden by other data attributes declared in the same element.
- Update docs example.
- Determine if we can find a way to merge these data attributes, regardless of their definition order.
- Determine if we want to deprecate/remove this helper. As it's barely used through our codebase, and it doesn't support the current taxonomy fully. We could also limit it to backend only, as it has some value there.
