Can't scroll search results with mouse or touch

I'm pretty sure this is a regression, but it affects Kiwix JS PWA as well, and may have been introduced with the new scrolling away system. It's still possible to use the keyboard (down arrow) to scroll through all the results, but we possibly have to add code in one of the captured events for scroll or for mousewheel (and also touch swipe) to scroll the search results list if the results are displayed.

Or it may just be a case of needing to enable overflow on the search div when the prefix field is focused. It would also be good to increase the z-index of search results so that they display on top of the bottom toolbar instead of underneath it.
