Pull Request Overview

This PR addresses an issue where creating a new nested document did not update the variant breadcrumb correctly until a page refresh.

• Replaces conditional slicing with filtering based on the current item's unique ID
• Adds a guard for #workspaceContext before filtering out the current item from the breadcrumb structure

• Consider adding a unit test for this new filter logic to ensure breadcrumbs exclude the current item when creating nested documents.

this._structure = value.filter((structureItem) => structureItem.unique !== unique);
