Testing TTS voices in HA Cloud Audio Bug

**iOS device model, version and app version**

Model Name: iPhone 15 Pro
Software Version: 18.5
App version: 2025.5 (2025.1264)

**Home Assistant Core Version**

2025.5.3

**Describe the bug**
Testing multiple TTS voices, leaving the app for at least a minute or so, then returning causes all tested voices to play at once. It made me laugh but also jump lmao

**To Reproduce**
Issue happens when testing multiple TTS voices under Settings > Home Assistant Cloud > TTS
Select language and voice, tap try, and play the voice, then go back, try another voice or language and repeat. Switch apps using home bar, in my case to safari, browse for a few minutes, then switch back to Home Assistant and it then plays all the voices tested simultaneously. This can be repeated by leaving the app again for a while then returning, you do not have to play the voices one by one again.

**Expected behavior**
Not being jump scared by a horde of helpful sounding robots.

**Screenshots**

Screen recording of the effect when returning.
