When navigating to an existing conversation in the Messages app, the initial placement of VoiceOver focus is higher in the thread than it should be

To reproduce this behaviour you will need to have an existing conversation in the Messages app which has at least several dozen messages.

1. Ensure that VoiceOver is enabled.
2. Open the native Messages app.
3. Place VoiceOver focus on to an existing conversation.
4. Double-tap with 1 finger.

You should now be taken to the conversation.

Note where VoiceOver focus is placed in the thread.

It will typically be 8-12 positions above the most recent message in the thread.

It does not appear to make any difference if the conversation has unread messages or if they have all been read.
