    Display a cumulative flow chart with a browser recognized as deprecated crashes the page
    Issue is present since the flow chart has been moved to D3 (request #12274).

    Reproduction steps:
    1. Add a cumulative flow chart of a tracker to a dashboard
    2. Try to access the cumulative flow chart with IE11 in compatibility mode
