Research direction
Investigate the CenterPopup and Steps component CSS to identify the cause of the dot jump during the popup open animation. Check the transition effects affecting the Steps component. The reproduction code is in the linked CodeSandbox. Look for any CSS properties like transform or opacity that might affect layout. Compare the animation of the popup with the Steps' internal positioning. Potential fix could involve using will change or adjusting animation timing.
