Kiosk mode: iOS kiosk mode brightness persisting after leaving the app

**iOS device model, version and app version**
iPad Air 5th gen, iOS 26.4.1

Model Name:
Software Version:
App version: 2026.4.1 (Build 2026.1873)

**Home Assistant Core Version**
2026.5.3

**Describe the bug**
iOS beta 2026.5.0 (2026.1984) was released yesterday, and the changelog states that this fix is included (‘fixed Kiosk Mode brightness persisting after leaving the app’). The issue should have been fixed in this PR: https://github.com/home-assistant/iOS/pull/4532

Unfortunately, the fix does not seem to work; if you open another app via, for example, a push notification, the dimmed brightness remains and does not increase. I am testing this via an automation where I send a push notification with ‘data: url: Welcome://’ and, when I click on it, the iOS Welcome app opens. The same happens if you open another app via the app switcher, it doesn’t work

**To Reproduce**
Open the home assistant iOS App in Kiosk Mode and wait for Screensaver with dimmed brightness. Wait for an notification from another app and press on it.

**Expected behavior**
The brightness should come back when switching to another app.
