Fix T88060: Expand freezing when deleting a Face Set with multiple loose parts
When checking if the mesh has only one Face Set only the current active
component for expand needs to be checked. Otherwhise other components
that won't be modified by Expand that contain other IDs will be taken
into account, making the Face Set deletion go into an infinite loop.
