Problem with `isfile_casesensitive()` on Windows about julia

[kimikage]

Or, (on Julia v1.11 and later)

function Base.isfile_casesensitive(path)
    Base.isaccessiblefile(path) || return false  # Fail fast
    name = basename(path)
    try
        for entry in Base.Filesystem._readdirx(dirname(path), sort = false)
            entry.name == name && return true
        end
    catch err
        isa(err, Base.IOError) || rethrow()
    end
    return false
end

Why should it succeed for paths that contain non-existent directories (even if they are cancelled out by ..)?
