<p>In the first div, open-on resolves both 'bc' to (<span class="error">&#91;title=&quot;a&quot;&#93;</span> .bc), that is incorrect. It does not see the difference between (<span class="error">&#91;title=&quot;a&quot;&#93;</span> .bc) and (<span class="error">&#91;title=&quot;a&quot;&#93;</span>.bc). But these two rules are quite different, first defines class 'bc' for a node that has an ancestor with title="a", while the second defines class 'bc' for a node with title="a".</p>

<p>In the second div, open-on resolves both cases of 's1' to (div * .s1); but only the last case is correct.</p>

<p>In css rules, white spaces always separate parent node restrictions from child node restrictions.</p></div>
