With those minimal changes, the following stories work/don't work:

• :white_check_mark: Single Selection
• :white_check_mark: Multiple
• :white_check_mark: Header
• :white_check_mark: Options Footer
• :white_check_mark: Filtered
• :white_check_mark: Filtered Picked
• :white_check_mark: Filtered Placeholder
• :x: Custom List Options (very easy / trivial; needs rework of the story)
• :x: Individual Custom Option (very easy / trivial; needs rework of the story)
• :white_check_mark: Custom Button Text
• :white_check_mark: Source Empty Placeholder
• :white_check_mark: Picked Empty Component
• :white_check_mark: Reordering
• :x: Increased Options Height (very easy / trivial; but has the risk of not working cross-browser)
• :white_check_mark: Different Widths
• :white_check_mark: Custom Filtering With Filter Input
• :white_check_mark: Custom Filtering Without Filter Input
• :x: Infinite Loading (the only issue that's not trivial)
• :white_check_mark: Loading Source
• :white_check_mark: Loading Picked
• :white_check_mark: RTL
