Scrollable container doesn't show scrollbar
Hi there,
I have the following setup duplicated thrice in my project - to select three distinct parameters to define an object.

Each listLayout is programmatically populated with a number of items (buttons).
One screen has 5 items, the other two have 6. Five items fit perfectly on a screen and don't require a scrollbar, while six items require scrolling to see the final item.
However, none of the scrollableContainer display their scrollbar until I touch the screen, despite me configuring it to do so (at least, that's what I think "Show scrollbars" means):

What am I doing wrong? How can I ensure that the vertical scroll bar is shown, by default, when I open a screen with more items than fit on a screen?
Thanks,
Julia
