+# Tests using placeholder-focus-ref.html as a reference are disabled because

+# text colour without changing the caret which means that the tested page has
+# a black caret with a grey text and the reference has a grey caret with grey
+# text. The only thing that is doable is to make the caret grey in the tested
+# page but that would make the test moot because a failure wouldn't be seen.
+# A real way to fix this would be to be able to style the caret or to implement
