From the audit #3966 we found out that PanelsContainer from

OpenSearch-Dashboards/src/plugins/opensearch_dashboards_react/public/split_panel/containers/panel_container.tsx

Line 54 in 55b293a

export function PanelsContainer({

have OUI Component that replaces it OuiResizableContainer. So, we probably should remove it after we replace all instances where PanelsContainer is used.

Leaving this for additional context.
