Is it better to wait until after Tisha Beav for saying Kiddush Levana? Is it permitted then immediately?

Remah (O.H. 426: 2) rules that Kiddush Levana should be recited after Tisha Beav. On question 2499 in regards to dancing on Kidush Levana on Motzei Tisha B’Av mentions that since the Remo considers the dancing a mitzvah it should be permitted even in the state of Avelus still present at the end of the fast. The dance is done to foster our belief in the Geula, since in Tisha B’av the Messiah was born. He adds that this is the common accepted tradition.
