For some reason as of version 133.0b2, tabs can no longer be dragged by clicking on them from the upper row, and will often automatically slip to the left if you try to move them that way.
Also, a single tab within tab groups with around 8 tabs can also no longer be moved, as it will remain in its current position.
The only way to drag tabs where you want is to use the List All Tabs function on the upper bar and drag them from there, or to move a tab to a new window, and move it back to the old window where you want to slot it.
