Why the Pin option in pop-right Sidebar windows is global for all Sidebar windows?!

I was testing latest Changelog entries for newest Opera Stable and I pinned Player (Opera Dev). I forgot to unpin that window, then I opened one website from the Custom site panels and it happened to be pinned, as well!

The Pin option needs to work independently.
