Hi there

I think I have found a solution to this issue. For the TopicCard.component.tsx on line 158, an additional block of code should be added so that, whenever a topic card is clicked, the entire page would scroll to the top.

This is the block of code that should be added:
window.scrollTo({ top: 0, left: 0, behavior: 'smooth' })

Do let me know how I can create a pull request for this :)
