Agent Panel: Copying Agent responses to clipboard results in duplicate or incomplete text

[xab3r]

Summary

Description

When copying agent responses from the Agent Panel (text thread), the clipboard content is duplicated and/or truncated

Steps to Reproduce

Scenario 1:

1. Start a new text thread.
2. Ask the agent a question. Let it generate single line answer.
3. Use the editor: copy command to copy the agent’s full response.
4. Paste the content elsewhere.

Result: The pasted text appears twice (duplicated).

Scenario 2:

1. Start a new text thread.
2. Ask the agent a question that results in a multi-line answer.
3. Use the editor: copy command to copy the full response.
4. Paste the content elsewhere.

Result: Only the first line is copied and pasted, and it appears twice.

Scenario 3:

1. Start a new text thread.
2. Ask the agent a question that results in a multi-line answer.
3. Copy a few lines of the agent’s answer, excluding the first line, using the editor: copy command.
4. Paste the content elsewhere.

Result: The pasted text appears as expected (no issues).

---

Actual Behavior:

• When copying the entire single-line response, the pasted text is duplicated (concatenated with itself).
• When selecting and copying the whole multi-line response, only first line is pasted (and appears twice); the rest of the content is missing.
• Copying lines other than the first one (i.e., not including the first line in the selection) works as expected.

Expected Behavior:

• The selected text should be copied exactly as it appears, without duplication or truncation.

Note: I've observed that this issue seems to occur during the copy operation itself, as using the editor: copy and trim command produces the correct behaviour.
