This rule is supposed to remove the top border of the first row of a table in a panel (as its direct child).
However, it also affects all rows in tables which are children of this first row.
Adding the "direct child" selector fixes this issue.
I believe this rule could be further modified to prevent the repetition of > .table > tbody:first-child > tr:first-child, but I have no knowledge of LESS therefore I'll leave that to someone more seasoned.
