Regression - Restore revision problems

• Create a new document, add some content and publish it. See attached img 'revisions 1.jpg'
• Edit the document, re-publish it. See img 2
• Now go to the revisions and restore the last one. A new tab is opened that shows the compare view of the selected revision and current published variant. Like in img 3
• On this tab, click Publication. The option to publish is not available. See 4. This is problem A
• Press 'Edit'. Suddenly the Administration button appears. See 5. The only option in that button is to 'Unlock'. This is problem B
• Unlock the document, or better close the 2nd tab shown from screenshot 3 and later (the grayed out one). Then you can press the 'Edit' button again. This time, a new tab is opened (or if you only unlocked, that 2nd tab is used) where I expected the revision contents, but I see the published content. See 6. This is problem C

Problem A: The document is in draft mode with a stateSummary of live. Isn't this wrong?
Problem B: The opened revision is locked cause there's another tab with the current version of the document open (pic 3). When you click on a revision, a new tab is opened but the one you started with stays also open. If you close that tab, or press unlock on the other, then the tab you end up with is again, the current. Not the revision. That explains problem C
Problem C: Well this means I can never see my document with content from a revision. The closest I come seeing my revision content is in the compare mode (pic 3)
