Description
Task Description
The facet-placeholder functional component has been migrated, but due to miscommunication it was integrated in the atomic-facet-placeholder custom element during the atomic-facet migration.
We can get rid of facet-placeholder.ts and facet-placeholder.spec.ts; it’s dead code
Acceptance Criteria
- facet-placeholder.ts has been deleted.
- facet-placeholder.spec.ts has been deleted.
- No other files have been touched.
