Sample Content to Print

This is sample content that should appear in the print preview.

• Item 1: Testing print functionality
• Item 2: Verifying dialog appearance
• Item 3: Checking modal behavior

Technical Details:

The bug was caused by passing a raw void* pointer instead of the properly cast NSWindow* to runOperationModalForWindow:.

Note: window.print() may not be natively supported in WKWebView. The Go API uses NSPrintOperation instead.
