QSslCertificate: subjectInfo() and issuerInfo() documentation does not reflect new return type

With Qt5, the return type of the subjectInfo() and issuerInfo() methods of QSslCertificate where changed from QString to QStringList. The documentation for subjectInfo(SubjectInfo) states:

Returns the information for the subject, or an empty string if there is no information for subject in the certificate.

This (a) talks about returning an empty string if there is no information, and (b) does not explain what values the returned QStringList contains or in what cases it contains multiple values.

The same applies to issuerInfo().
