parse_declarations! splits blocks on semicolons unless the the semicolon appears inside parentheses. Because there's no equivalent exception for quotation marks, strings containing semicolons get split. This means we lose any text after the semicolon.

For example, this CSS

.test-1 {
  display: grid;
  content: "I came; I saw; I conquered.";
}

gets split into the following declarations, eating a chunk of the content value:

rules:
 #<CssParser::RuleSet:0x0000000122194150
  @declarations=
   #<CssParser::RuleSet::Declarations:0x0000000122193d18
    @declarations=
     {"display" => #<CssParser::RuleSet::Declarations::Value:0x00000001221932c8 @important=false, @value="grid">,
      "content" => #<CssParser::RuleSet::Declarations::Value:0x0000000122192dc8 @important=false, @value="\"I came">}>,
  @selectors=[".test-1"],
  @specificity=nil>}]
