Problem fixed, thanks guys

Updated to 83.0.4254.19 yesterday, still doesnt work for me

Since I updated to version 82.0.4227.58, Opera is automatically resizing remaining tabs when I close one tab.
So if I want to close more than one tab by clicking the mouse wheel, the remaining tabs will adjuste their size (and move) and causes accidentally closing the wrong tabs.
Until I updated Opera, the tabs stayed in place until the cursor was moved away from the tab bar and were only adjusted afterwards.

How can I restore its old behaviour?

Thanks in advance
