Description

Fixes an issue where square brackets on the first line of code blocks were incorrectly interpreted as block titles.

For example, C# attributes like [Flags] at the beginning of code blocks were being parsed as the title instead of being treated as part of the code content.

Changes

• Modified the regex in code-wrapper.ts to only match spaces and tabs (not newlines) on the opening line
• Changed \s* to [ \t]* to prevent matching newlines before parsing optional title brackets
• Added test cases to verify the fix works correctly with and without titles

Test Cases

1. Code block with square brackets but no title - ensures [Flags] stays in code
2. Code block with both a title and square brackets in code - ensures both work correctly

Before (Current Behavior)

The first test case incorrectly extracts [Flags] as the title:

 exports[`code-wrapper with square brackets in code 1`] = `
 "
 
-<CodeBlockWrapper v-bind="{}" :title='"Flags"' :ranges='[]'>
+<CodeBlockWrapper v-bind="{}" :title='""' :ranges='[]'>
 
-\`\`\`csharp [Flags]
+\`\`\`csharp
+[Flags]
 enum MyEnum {}
 \`\`\`
 
 </CodeBlockWrapper>
 "
 `;

Visual Example

The following C# code demonstrates the issue:

[Flags]
public enum Permission
{
    None = 0,    // 0000
    Read = 1,    // 0001
    Write = 2,   // 0010
    Delete = 4   // 0100
}
