Regression in Gerrit regarding rebases from Gerrit UI

Hi!

It seems I am experiencing a regression in Gerrit regarding the rebase capability available from the Gerrit UI. Before, when a child patch (in a patch stack) had its parent patch modified, it was possible to quickly rebase on the current state of the parent patch via the rebase button. Now, Gerrit UI always claims "This change is up to date with its parent." and suggests rebasing on top of the branch or any other patch.

Just reporting this issue to see if others also experience this behaviour or something broke on my side (however unlikely).
