GPT-generated messages suddenly became non-selectable —
unless I explicitly enter “Select Text” mode first.

Normally, user messages and GPT messages are selectable in the same way.
But now it feels like GPT output has been moved into a different UI rendering lane.

🧪 What I observed

• Tapping on a GPT message shows no selection handles
• Long-pressing offers only high-level options (“Copy”, “Select Text”, etc.)
• Only after choosing “Select Text” do the selection handles appear
• This applies only to GPT output, not user messages

📎 Hypothesis

This might be a new UI-layer separation for GPT output —
a container split or safe-rendering lane introduced in the 5.1 wave.

If so, this is the first time I’ve seen GPT messages become functionally isolated from the rest of the chat UI.

❓ Anyone else seeing this?

• Is this happening on your Android app?
• Is it an intentional safety layer?
• A rendering bug?
• Or a silent UI experiment rolling out?

Curious to hear if others can reproduce it.
