Description: floating DOM elements and chart components are incorrectly overlapping and obscuring the scrolling bars within the application.

Expected behavior

Floating elements and charts should not interfere with scrolling bar functionality  Scrolling bars should remain fully accessible and clickable at all times  Proper z-index layering should ensure scrolling bars remain on top or floating elements are positioned to avoid overlap

Actual behavior

Scrolling bars are covered by floating DOM elements  Users cannot interact with scrolling bars when overlapped
