ScrollPanel: Null Reference Error in iOS Safari/WKWebView

[madalina-agh]

Describe the bug

Environment:

• Next.js PWA
• Mobile Safari/WKWebView browser
• Route change scenario (specifically during rapid logout)

Error Details:

• TypeError: null is not an object (evaluating 'I.current.scrollWidth')
• Occurs when ScrollPanel is quickly removed from DOM during route change

Potential Cause:
Incomplete unmounting or cleanup processes might be leaving unresolved references to the ScrollPanel component.

Proposed Solution:
Implement null checks in the ScrollPanel component to prevent null reference errors during rapid DOM manipulations.

Additional Notes:
Error has only been observed in iOS Safari/WKWebView environment.
