What type of issue is this?

Incorrect support data (example: BrowserX says "86" but support was added in "40")

What information was incorrect, unhelpful, or incomplete?

These four are script-specific generic family names, added to CSS spec draft recently. First, they should be used through generic(xxx) syntax, instead of naked xxx. Second, they do not work on any browser.

NOTE: You may have the illusion that fangsong/kai are supported. But actually it's just that coincidentally, windows has a font named "fangsong" and macos has a font named "kai". But font-family: fangsong doesn't work on macos, and font-family: kai doesn't work on windows.

What browsers does this problem apply to, if applicable?

No response

What did you expect to see?

These four rows removed, since no browser support that. They're still in draft stage.

Did you test this? If so, how?

Tested on latest version of edge, chrome and firefox on windows 11. And tested on latest version of safari, chrome and firefox on macos 15.
