In preparation for #984, start drafting the selection component without any proper styling. Some things that should be considered:

• It should be possible to provide a searchable list of hundreds of list items. Therefore, we should keep an eye out for the performance.
  • The items should only be rendered when the popover is opened
  • Is there a way to only render in the viewport currently displayed elements? (e.g. for Angular exists virtual scrolling, here's a native example which implementation seems very extensive)
• Have a look at our autocomplete component
  • it's quite similar to the selection component besides the input being the host of the popover
  • the library we use in the autocomplete can probably be used in this one as well
  • are there any parts that we can share between the two components? How?
• Ensure that things like accents are properly handled (e.g.: searching for Jan should also yield Jàn). Have a look at the native localeCompare string method and the sensibility option (also get in touch with me as I've implemented this case just recently)
• Does a similar library already exist that we can use?
