O que costuma-se supor
The CSS attribute selector [attr~="val"] treats hyphens as word boundaries and matches substrings in hyphenated attribute values.
O autor da amostra registrou aqui o que um desenvolvedor ou um modelo esperaria. O contrato abaixo é o que de fato rodou.
Contrato
- child.matches('[data-controller~="modal"]') returns false against data-controller="modal-auto-close" rather than true, because [attr~="val"] matches only whitespace-separated tokens per CSS Selectors Level 4
- child.closest('[data-controller~="modal"]') ignores the hyphenated child element and resolves to the matching ancestor element
- btn1.matches('[class~="btn"]') returns false on class="btn-primary"
- btn2.matches('[class~="btn"]') returns true on whitespace-delimited class="btn btn-primary"
