Cannot use chat right click menu until chat scrolls up several lines

So it's obviously very important to be able to quickly invite people after they message you for a trade. The average player has the attention span of a gnat, so you lose the sale if you don't reply in 3 seconds. That's why you really need to fix this bug that makes it impossible to interact with the right click menu that allows you to invite players until chat has scrolled up several lines. You can right click and open the menu that's supposed to allow you to invite the player, but clicking on "invite" does nothing. This feels almost surgically targeted to make the already very frustrating trading process even worse
