On Global Administration, when clicking on a rule name and selecting "Open link in new tab" it shows the list of all rules instead. The same happens if you select "Open link in new window".
The expected behavior was to open the Rule's details of the rule you've selected.
This also does not work if the “Copy link address” option in the right-button menu is selected. It rarely works and only if you wait for each rule to be loaded and only after this open another tab with another rule.
