Audio playback cuts off too early

**Describe the bug**
In my current configuration, the audio playback in audio annotation tasks cuts off too early and stops ~500 ms before the actual end of the audio file. When creating and playing a region which covers the audio file length, the missing file end will be played back correctly.

**To Reproduce**
Steps to reproduce the behavior:
1. Create audio annotation tasks with transcript labeling
2. Store audio files locally and connect correspondingly with local source storage
3. Insert labeling interface code:
```

</View>

<View style="width:40%; min-width:500px; max-height:70vh; overflow:auto;
padding:12px; border:1px solid #ddd; border-radius:8px;">
<Header value="Reference transcript"/>
<Text name="ref" value="$context_transcript"/>
</View>

</View>
```
5. Play audio file
6. See error: Audio files does not playback until actual end

**Expected behavior**
Playback should cover the whole audio file duration.

**Environment:**
- macOS 26.3.1
- Label Studio 1.23.0
- Firefox 149.0

**Additional context**
- Source storage are local audio files
- changing the player version did not help
- changing the decoder did not help
- issue persists across different browsers (Firefox and Safari)
