Transitive re-renders on hovering same itinerary at different time

[binh-dam-ibigroup]

For batch routing, hovering between identical itineraries starting at different times triggers a render of each itinerary hovered. This is a subtle behavior that is not noticeable on the UI but may result in extra unnecessary computation.

For testing:

• Checkout the Transitive styles #366 or more recent branch (the behavior exists on the dev branch prior to that nonetheless).
• Add a console.log('Transitive render') statement at this line
• Try this query
• Hover between the two Walk-to-rail itineraries.
• Observe the added console logs being printed.
