Webstorm, add space to beginning and end of HTML comments

Question

Does anyone know how I can change the style of HTML comments in Webstorm?

Atm if I use cmd+/ to comment out a line, I get

retcode

How do I add a space to the start and end of 'Message' so that it becomes

std::unique_ptr<T> ctx = foo();
auto transaction = ldapInterface.get_transaction(); // will rollback unless committed
certman::set_cmp_server_psk_refnum(*ctx,domain,nullptr,nullptr,0);
transaction.commit();
