Fix: Prevent Override of Existing innerCustomChildren

[luzmcosta]

Because the existingChildren check references customChildren but the render uses the customInnerChildren property, this plugin resets customInnerChildren, overriding previous children, thereby preventing other extensions from rendering. Fixing the check to inspect customInnerChildren allows this extension to co-exist with other extensions leveraging the customInnerChildren property.
