<p dir="auto">Due to the way that we process semicolons as delineators for multiple values, we currently discard trailing semicolons. This isn't intentional.</p>
<p dir="auto">The value of every tag shown is processed to some extent, the value <code class="notranslate">|white;</code> is handled here:</p>

<p dir="auto">In Ruby, String#split discards any trailing null values, but this can be overridden by a passing a negative limit (i.e. to return all parts).</p>
