/**
 * Custom HardBreak extension that extends the default TipTap HardBreak.
 *
 * This extension modifies the DOM rendering to include a zero-width space
 * after the <br> element. This helps with cursor visibility when the cursor
 * is positioned right after a hardBreak (e.g., before an inline node like a variable).
 *
 * Without this, the browser has no text node to anchor the cursor, making it invisible
 * even though ProseMirror knows the correct cursor position.
