🔧 Fix: Excessive Line Spacing in Markdown-rendered User Messages

[ohneda]

Summary

This PR addresses an issue where excessive line spacing was added　when rendering user messages in Markdown format, resulting in an unintended appearance.

Before:

After fix:

User message rendered in markdown

User message rendered as plain text

Details

Currently, Markdown-rendered user messages have a whitespace-pre-wrap class applied to their wrapper div. This class introduces extra line spacing in markdown text.

This fix removes the whitespace-pre-wrap class from the wrapper div for markdown-rendered user messages, ensuring the line spacing is consistent and appropriate.

Please let me know if this solution isn't suitable.
