Custom Chinese font is overridden

[shellRaining]

Describe the bug

After updating to the latest version of vitepress, I found that my custom font was overridden. I have specified the font as LXGW WenKai, but it is overridden by the higher-level selector :root:lang(zh)

Reproduction

@import url("https://cdn.jsdelivr.net/gh/CMBill/lxgw-wenkai-web/style.css");

:root {
  --vp-font-family-base: "LXGW WenKai";
  --vp-font-family-mono: "LXGW WenKai Mono", monospace;
}

The above is the code of my font.css.

import DefaultTheme from "vitepress/theme-without-fonts";
import "./fonts.css";
import "./custom.css";

export default {
  extends: DefaultTheme,
}

This is how I use it

Expected behavior

Display the correct font and modify the document to provide the latest practices.

I guess the problem comes from this piece of code

vitepress/src/client/theme-default/styles/vars.css

Lines 271 to 276 in 0cbb469

	:root:lang(zh) {
	--vp-font-family-base: 'Punctuation SC', 'Inter', ui-sans-serif, system-ui,
	'PingFang SC', 'Noto Sans CJK SC', 'Noto Sans SC', 'Heiti SC', 'DengXian',
	'Microsoft YaHei', sans-serif, 'Apple Color Emoji', 'Segoe UI Emoji',
	'Segoe UI Symbol', 'Noto Color Emoji';
	}

I added the following code to increase the priority of my CSS selector, and it seems to have solved it.

:root[lang] {
  --vp-font-family-base: "LXGW WenKai";
  --vp-font-family-mono: "LXGW WenKai Mono", monospace;
}
