Display timeline at top when scrolling on shared webpage

When we create a starter roadmap in Aha and scroll down, the timeline stays intact at the top so its easy to see timeline for items that we scrolling. But we share the same roadmap via share webpage option and scroll down the webpage, the timeline is not intact at the top and it goes away. This makes it difficult for other stakeholers who do not have access to Aha to see the timeline across all items on the roadmap.
