DecorationRenderOptions问题：为指定范围文本添加蓝色下划线异常

Text Styling #

• Italicized text uses single asterisks for emphasis.
• Inline code snippets like npm install are wrapped in backticks.

Block quotes start with a greater-than sign, ideal for highlighting quoted content.

Unordered Lists #

• First list item
• Second list item
  • Nested sub-item 1
  • Nested sub-item 2

Links & Images #

• Internal Guide (relative link example)
• User Avatar (image with descriptive alt text)

Multi-line Code Block #

function handleClick() {
  console.log("Button clicked!");
  document.body.style.backgroundColor = "#f0f0f0";
}
