This pull request includes changes to the AnalysisPanel component in the app/frontend/src/components/AnalysisPanel/AnalysisPanel.tsx file. The updates introduce a new state variable to manage the selected tab in the Pivot component and ensure the tab is reset when an active citation is selected.

Key changes:

State Management Enhancements:

• Added a new state variable innerPivotTab to manage the selected tab in the Pivot component. (app/frontend/src/components/AnalysisPanel/AnalysisPanel.tsx, app/frontend/src/components/AnalysisPanel/AnalysisPanel.tsxR35-R36)

Effect Hook Updates:

• Updated the useEffect hook to reset the innerPivotTab to 'indexedFile' whenever activeCitation changes. (app/frontend/src/components/AnalysisPanel/AnalysisPanel.tsx, app/frontend/src/components/AnalysisPanel/AnalysisPanel.tsxR104-R106)

Pivot Component Updates:

• Modified the Pivot component to use the innerPivotTab state for the selectedKey prop and added an onLinkClick handler to update the state when a different tab is selected.
