Problem with FileDropzone component


I am creating an App plugin in Grafana using the template. The thing is that I have decided to use the Grafana UI component library and using FileDropzone as a component I don’t quite know how I can style the file list.
My problem is that I have used the component inside a div, and to this div I have given some fixed sizes and an auto overflow so that I get the scroll.
Here with few files (it looks just as I want)

Here with many files (I have to delete files to visualize the drag and drop since I can not scroll more)
