The already-relegated Owls had lost 16 of their previous 17 games, but City failed to beat them on Easter Monday, missing a chance to move out of the relegation zone.
Leicester conceded inside 90 seconds, with Rowett admitting Wednesday showed more aggression at a set-piece to win the 50-50s and set up a tap-in for Jerry Yates.
City had 24 shots, 12 on target, and eventually broke through with Jordan Ayew’s late leveller, but they also found the woodwork and an inspired Sheffield Wednesday keeper in the way.

They had a penalty appeal turned down as well, with substitute Jannik Vestergaard’s shirt pulled at a set-piece.
> “It’s hugely frustrating. What you can’t do is give them a lift. And that’s what we did after a minute and a half. It’s quite ridiculous,” Rowett said.
“It was more or less the first time they put the ball in the box. They land on it, they score, they’re a bit more aggressive. I’ve said it before, that’s been a huge problem for us.
“We’ve had most of the ball, most of the chances. They’ve had one shot on target; we’ve had five or six incredible chances. The keeper’s made four or five very good saves. We’ve hit the post, we’ve hit the bar. We’re disappointed with how we’ve played, but we’ve done more than enough to win.
“We should have had a penalty as well. Jannik Vestergaard gets dragged down in the box, his shirt pulled about a foot away from his body. I don’t understand why that’s not a penalty.
“Sometimes we rushed things, sometimes we showed patience. When we rushed, it looked frantic, like a side too desperate to get back into the game. I’m disappointed we’ve not won, and that’s the overriding feeling.”
With all games between the bottom six ending in draws on Monday, City remain one point from safety, with only five matches remaining.
