Here's a reproduction:

<!DOCTYPE html>
<p>dummy text</p>
<style>
p { color: blue; }
</style>
<script>
function print(text) { 
 document.body.appendChild(document.createTextNode(text));
 document.body.appendChild(document.createElement('br')); 
}
print("For gMCR(el), rules are '" + 
  getMatchedCSSRules(document.querySelector('p'))[0].cssText + "'");
print("For gMCR(el, 'before'), rules are '" + 
  getMatchedCSSRules(document.querySelector('p'), 'before') + "'");
print("For gMCR(el, 'foo'), rules are '" + 
  getMatchedCSSRules(document.querySelector('p'), 'foo')[0].cssText + "'");
</script>
