RFR: 8368166: Media query should accept multiple rules [v2]

[Michael Strauß]

> Given a media query with more than one rule:
> 
> 
> @media (prefers-color-scheme: dark) {
>     .foo1 {
>         -fx-background-color: black;
>     }
>     .foo2 {
>         -fx-background-color: white;
>     }
> }
> 
> 
> The following CSS parser error is encountered: `Expected RBRACE`
> 
> The reason for this bug is that the CSS parser mistakenly expects that after the first rule was parsed, the media query should be terminated with a closing curly brace. This is obviously incorrect, the fix is relatively simple.

Michael Strauß has updated the pull request incrementally with one additional commit since the last revision:

  emit error when closing curly brace is missing
