I'm not sure if this is as minimal as it could be but based on a demo (https://codepen.io/editor/WickyNilliams/pen/019dba7a-6160-76db-95df-6ba3cfcd17b8) I've found a bug in safari tech previews currently base appearance select where it'll render a select without rendering its options correctly. A more minimal version can be found at: https://codepen.io/lukewarlow/pen/GgjbWOW - it seems related to shadow roots but I can't only reproduce it with imperative shadow dom, not declarative.
