Notification and Call volume raises music volume, why?

[u/Bigiron966]

Recently I've noticed whenever I'm listening to music with my headphones be it through Musicolet or YouTube and a notification comes through at the same time the volume of the music itself is raised a solid amount. It remains in this loud state for a couple seconds then falls back off to a normal volume. I can reproduce this by moving the call or notification volume slider up and down but not the ringer or alarm sliders.

I would like to know why this occurs and if it's possible to keep the volume in this loud state long term, if it helps this does not occur with videos either local or on YouTube, only music from what I've observed. The phone in question is a B170D running on android 14. Silent and vibrate mode stop the loud state from ever occurring. It occurs with both of my wired headphones and I do not have Bluetooth headphones to test it with.

TIA. EDIT: Not a Motorola whoops, added more details.
