As per description, the right pane of signature window, when a certificate is selected in the left pane, doesn't display the status at all.
In AOO it doesn't happen.
In Libo the remaining partial status data, when a certificate element is selected, are displayed.
It appears that LibO refreshes the GUI API windows in reverse order wrt AOO.
A new configuration flag will be available in the options, to select between the two (AOO or LibO) interfaces.
