Display and operation issues of quoted content in the chat panel

What happened

When the quoted content is relatively long, the quoted content cannot be deleted as the close button is obscured. It is expected to place the close button on the left‑hand area of the item.

Steps to reproduce

1. connect agent
2. Quote a selected content
3. Drag the chat panel to its narrowest width
