False error in syntax highlighting when using `has`

[sanjarcode]

Describe the bug

I'm using the has keyword in CSS, and for a complex case, the editor shows an error (red squiggly lines).
The CSS is correct and works just fine. I verified it works in vscode editor.

Browser

Version 141.0.7390.77 (Official Build) (arm64)
macOS Tahoe 26.0.1

To Reproduce

Open the Stylebot editor (on any site) and paste this code

[data-actions-expanded] [aria-label='Options']{
  background-color: red;
}

div:has(> * > [aria-label="Edit event"]) {
  background-color: green;
}

Expected behavior

Red lines shouldn't be shown

Screenshots

Additional context

I think syntax highlight package needs to be updated.
