How to stop exit of overlay from returning to top of the scene

I'm using the infinite scroll and in one of my scense I have choosen to use the overlay to have "pop ups" to give more details of the topic. However once the overlay is exited the scene goes back to the top rather than staying where the material is, for example in the middle of the scene or even towards the end. How can I prevent that, so the learner doens't have to scroll back down to the list of topics that they need to click? If overlay isn't a good option then what can be used instead to ensure once they close the "pop out" it stays on the list.
