Always render all slots

List height is determined by item height and visible items number (`remain` prop) and this works flawless as long as this number is {Integer}. But... when `remain` prop is set dynamically to {Float} (for ex.: list fills all available vertical space in UI), last item in scrollable list won't be rendered (for ex.: `delta.end' can equal `58.6` for `59` items, so only 58 slots are rendered).

This solution fixes the problem.
