This is a short-term regression fix that was unfortunately not merged in time.
It is anticipated that @mizvekov will put up an ultimate fix of lambda context declaration in Clang 20, so this will be superseded eventually. However, given that it still takes time for Matheus to complete his patch, we backport this one to avoid regressing some cases reported in 19.
