Description: When generating chatbot responses in Chainlit, extra blank spaces appear inconsistently between list items and after headings.

• The raw LLM output is correct (verified in other markdown renderers).
• Issue occurs intermittently, not always reproducible.
• Thought Removing bold syntax (**Text**:) may causes it does not resolve the problem.

Steps to Reproduce:

1. Generate a response with lists, headings, and bold text.
2. Observe random blank spaces introduced in the rendered output.

Expected Behavior: Markdown should render consistently without extra blank lines.

Actual Behavior: Random blank spaces appear, making formatting unreliable.

Environment:

• Chainlit version: 2.7.2
• Browser: FireFox/Brave
