Steps to reproduce:

This problem happens on Windows. Browser language is zh-hans.

Open two Wikipedia pages:

https://zh.wikipedia.org/wiki/%E5%88%A9%E9%9A%86%E5%9C%AD
https://wuu.wikipedia.org/wiki/%E5%88%A9%E9%9A%86%E5%9C%AD


Actual results:

Both the font-family for h1 and h2 title is "Linux Libertine", Georgia, Times, serif. Chinese characters fall back in 'serif'. But there is a differnce between the two pages:

(Correct)
In Zh version, the title shows serif font (SimSun).

(Wrong)
In Wuu version, the title shows sans-serif font (Microsoft YaHei).


Expected results:

Serif Chinese characters should show serif font in any condition.

I have this problem as well, except with Japanese text instead of Chinese. My system is configured to use Source Serif Pro and Source Sans Pro, falling back to IPAMincho and IPAGothic. With lang="ja" IPAMincho is used for both Latin and CJK, while without it Source Serif Pro is used for Latin text and IPAGothic is used for the CJK text.

Here is a test case I cooked up.
data:text/html,<html><meta charset="utf-8"><p style="font-family: serif;">Here is some text. こんにちは<p style="font-family: serif;" lang="ja">Here is some text. こんにちは

This has worked correctly for me in the past.
We don't have Wu Chinese mapping for font...
