Timeline alignment:

• PR Super wide RHP  #77657 merged: 2026-01-15 at 11:59:59Z
• Bug reported: 2026-01-15 at 20:35:40Z (caught during regression testing of PR [Part 3]: Remove Onyx.connect() for the key: ONYXKEYS.COLLECTION.TRANSACTION_VIOLATIONS in src/libs/TransactionUtils/index.ts #79196)

Root Cause

When the Super Wide RHP layout changes were introduced, the state management or data loading for expense details after deletion was disrupted. After deleting one of duplicate expenses, the remaining expense preview fails to properly load/display transaction details (merchant, category, etc.), showing only the total amount.

The issue likely stems from how the new RHP navigation handles report data updates after transaction deletion - the report may be reloading incorrectly or the transaction details are not being properly refreshed in the new layout structure.
