Good job as usual
Only a partial review ( around half of it ) 😵‍💫

Hello, few things to fix

[TomMenga]

LGTM 👍

[DavideMininni-Fincons]

Note for reviewers:
apparently, the autocomplete behavior (add bold style to options that match the typed text) was not working anymore due some changes related to SSR.

A fix was made in the commit 'fix: enable autocomplete behavior' 89538b1 but since i'm not fully aware of what exactly is rendered in SSR, the change should be reviewed.

Nice work! 😃
Some minor nitpicks, but there is an issue with the mini button base.
After that it should be good to merge!
