"Show more" button for references have incorrect white bars above and below the icon

[taldekar]

Describe the bug
The "Show more" buttons used to expand multiple references under the responses are not rendering correctly. There are unexpected white bars appearing above and below the button icon.

To Reproduce

1. Go to chat prompt and type "What are Java recursive functions and how does the recursive fibonacci implementation work? What is time complexity? How do you calculate it?"
2. The response should include multiple references, which you can access at the bottom of the response.
3. The button will not render correctly.

Expected behavior
The "Show more" button should appear as a clean, properly formatted button without any unexpected visual elements.
