I am not sure if this is intended behaviour but CTRL+TAB has an inverted tab swap. As I am personally coming from Msoft Edge, the CTRL+tab used to go through the tabs from left to right, not from right to left.
Even the popup screen inverts the tabs first(?), then scrolls from left to right.
I hope that this is useful information as I don't really like the CTRL+TAB function at the moment for quick tab switching
