In rBeaee2b411935 I removed BKE_sequencer_base_clipboard_pointers_store from paste function, because I wanted pasted strip to always reference copied strip, not recently pasted one. This worked well with ordinary strips, but not if they reference ID. Add back BKE_sequencer_base_clipboard_pointers_store call. I thought that always referencing original strip would be more correct approach, but it doesn't matter now. Referencing recently pasted seems to be cleanest way to do this.
