Tab stack moves to end when I drop something new into it
I have tabs at the top of the screen, showing a bit of thumbnail. I have a tab stack at the far left of the bar with a number of things on it. I usually keep it there out of the way (it's a bit of a "check this later" pile of tabs).
If I open a new tab (so it's on the far right), navigate somewhere and then drag/drop it into the tab stack, the entire stack moves to the far right. (I think it's basically wherever the tab I'm dragging was).
I don't think this is the right behaviour. It certainly annoys me anyway!
