Fix a bug with photo attachment picker not displaying

[martinmitrevski]

🎯 Goal

Seems like on iOS 18 the overlay updates are triggered differently, causing the checkmark in the photo picker not to display when tapping.

🛠 Implementation

Added an id identifier to be explicit about this.

🧪 Testing

Open the photo picker and tap on some images.

🎨 Changes

Add relevant screenshots or videos showcasing the changes.
