How about "#parent > div:-abp-contains(to hide)"? This is a slightly less
trivial scenario, sibling and toHide should be hidden.

Did you overlook this comment?

I did. but "#parent > div:-abp-contains(to hide)" will only select #sibling
since #tohide is not a direct child of #parent.

However "#parent div:-abp-contains(to hide)" will.

+    ["#parent div:-abp-contains(to hide)"]
   ).then(() =>
   {
     expectVisible(test, parent);
     expectVisible(test, middle);
     expectVisible(test, inside);
-    expectVisible(test, sibling);
+    expectHidden(test, sibling);
     expectVisible(test, sibling2);
     expectHidden(test, toHide);
   }).catch(unexpectedError.bind(test)).then(() => test.done());
 };
 
 exports.testPseudoClassHasSelectorWithPropSelector = function(test)
 {
   let parent = createElementWithStyle("{}");
   let child = createElementWithStyle("{background-color: #000}", parent);
   applyElemHideEmulation(
     ["div:-abp-has(:-abp-properties(background-color: rgb(0, 0, 0)))"]
   ).then(() =>
   {
     expectVisible(test, child);
     expectHidden(test, parent);
   }).catch(unexpectedError.bind(test)).then(() => test.done());
 };
