Trigger it by accident? Isn’t that like saying, that you can’t control your mouse? Or what is it that happens… I have many tabs open, all the time, I use groups too - and I have not once triggered it by accident. You have to hover over a tab, bit another tab, to activate it… and then, it is clearly visible, if you to - and then all you have to do, is move the tab a little away, to to remove the suggested group.
