Proposed resolution (approved by CWG 2022-06-17):

Change in 13.8.3.3 [temp.dep.expr] paragraph 3 as follows:

Expressions of the following forms are type-dependent only if the type specified by the type-id, simple-type-specifier, typename-specifier, or new-type-id is dependent, even if any subexpression is type-dependent:
simple-type-specifier ( expression-listopt )
simple-type-specifier braced-init-list
typename-specifier ( expression-listopt )
typename-specifier braced-init-list
...

[Accepted at the July, 2022 meeting.]

According to 13.8.3.3 [temp.dep.expr] paragraph 3,

...Expressions of the following forms are type-dependent only if the type specified by the type-id, simple-type-specifier or new-type-id is dependent, even if any subexpression is type-dependent:

    simple-type-specifier ( expression-list )
    ::opt new new-placementopt new-type-id new-initializeropt
    ::opt new new-placementopt ( type-id ) new-initializeropt
    dynamic_cast < type-id > ( expression )
    static_cast < type-id > ( expression )
    const_cast < type-id > ( expression )
    reinterpret_cast < type-id > ( expression )
    ( type-id ) cast-expression

This list is missing cases for:

    simple-type-specifier braced-init-list
    typename-specifier ( expression-listopt )
    typename-specifier braced-init-list
