Brett Ritchie got the Stars within 4-3 at 1:50 of the third period. It was his first goal in 22 games dating to Jan. 4.
Domingue remained in the game after his quad muscle cramped during overtime. The game was delayed more than three minutes while Domingue stretched.
"I wasn't going to put [No. 1 goalie Andrei Vasilevskiy] in net ice cold," Domingue said. "If someone's going to get hurt, I'd prefer it's me."
Bishop allowed five goals on 25 shots. It was his second loss to his former team this season; he allowed six goals on 28 shots in a 6-1 loss Nov. 16.
It was Miller's second game with the Lightning after being acquired in a trade from the New York Rangers on Monday.
