A couple of things:

• could you start filling the PR template we provide, especially the part regarding the tests? We don't ask for a lot of info, and since you've been contributing a lot lately, I believe it's only fair
• have you considered the solution proposed by Denis? 🐛 CSS parser does not recognize multiple semicolons after a declaration #3836 (comment)

ok, i will update the template later. i try to update the css.ungram like:

CssDeclarationWithSemicolon =
    declaration: CssDeclaration
    ';'*

But it will get an panic like:

And I've looked elsewhere and haven't seen similar writing methods. So i refer the statement JS_EMPTY_STAMENT of js parser and add a CSS_EMPTY_DECLARATION here.
