Bug: Audio with phone off when PiP is selected

[Dstendo]

When i select PiP in the Background Playback option in the app settings, then start a stream or vod and turn my phone off while in the Xtra app, the audio continues playing while the screen is off.
If i go to my home screen with the same settings while the video is playing in PiP and turn my phone off, the option behaves correctly and no audio plays.
If i select "Only Audio" it plays the audio both in phone standby with off screen and on the home screen in the background.
The issue persist both with no Bluetooth Headphones connected and with them connected.
Using Samsung S10 with newest updates.
In Xtra App settings version is 2.33.3.
Apk in Github release from 3rd August 2024

Steps to reproduce:

• Select "Picture in Picture" under "Background Playback" in the app settings
• Press power button while in the Xtra app to get phone into standby and turn the screen off
