It used to be that, while placing a bid in one tab led to failed security check errors when placing a bid on another tab, junking was unaffected by this. But in the last few months(?), I've noticed that at least sometimes, when I place a bid in one tab, junking cards in another doesn't work. Except that unlike with placing bids, the red error box doesn't show up—the junked animation plays, and everything looks normal, but then when you refresh the page or go to your deck, you still own the card.
I have not been able to consistently trigger this issue, but I've had it happen on Chrome desktop, Chrome mobile, and Firefox desktop.
