Exploding message doesn't not disapear on iOS

Hi.
I just saw that exploding messages on iOS doesn't work as expected.

Sent a message with a 30' timer.
Let the timer fuse.
"Boom!" appears on the right, with the message still there. The message will stay there till a new one or a display is changing (menu navigation etc.)
Same thing happend for pictures.

No file, test, or entry point is identified in the issue. Start by reproducing the 30-minute exploding-message behavior on iOS, including pictures, and observe whether the message remains until navigation or another message arrives. Done means the expired content disappears without requiring a display change.
