Picklist's menu styling issues #1037
Description
Iced's menu styling and rendering for picklist and combobox widgets is currently pretty limited and broken:
- can't specify a class for the scroller / scrollable
- can't specify properties for the scrollbar
- scroller style doesn't respond to hover events
- menu borders aren't respected when an option is hovered
- additionally, the combobox widget doesn't let you know the status/number of the currently filtered options, causing Sniffnet to display a longer menu height when filtering a menu with more than 9 total options
