Messages (and messages only) banners not showing when in Do Not Disturb

When I have my iPhone in Do Not Disturb mode and I get a notification, it doesn't make a sound or vibrate or light up the screen, but the banner for the notification still shows on the screen if I light it manually. This is the intended behavior. However, this is true for all apps *except* text messages.

In other words: I usually have DND on at night while I sleep, but if at any moment I wake up and light up my screen, I can see all the notification banners that were generated while DND was on, *except* for text messages. I would like to fix it so that text message notification banners *also* show up on the screen while DND is on like every other app. This used to be the behavior, but at some point with some update (or something I did) it stopped working as intended.

Any ideas? Thank you!
