RSSP Duplicate PRs with Attachments

When we duplicate a PR with attachments, the attachments do not show on the new PR. Is this expected behavior? We tried line level and header level, but no luck. I submitted an SR (4-0000728125). They told me a workaround, but we want to understand why this is different than SSP and want it fixed so they function the same. I was told to log a CCC to get answers about potential future fixes from the product management team.
