:kcochrane, since you are the author of the regressor, bug 1933479, could you take a look? Also, could you set the severity field?

I'm honestly not seeing what the problem is - the close button is overlaying the tab and therefore it requires some changes. Can you please clarify what specific part of vertical tab spacing you think shouldn't change?
