Two comments each carrying one apostrophe get paired into a single "string" spanning both — and every rule between them, plus the `*/` that should have closed the first comment, is swallowed and then deleted by the comment pass. This silently ate the whole `:root` token block out of every bundled theme, in production builds only (dev doesn't minify), which is the worst possible place for it to hide. - Comments first: `content: "/* not a comment */"` is a legal string value and must survive verbatim.</code></pre> </div> </div> <div class="tags"> </div> </dt> <dd><pre class="code"><span class='tstring'><span class='regexp_beg'>%r{</span><span class='tstring_content'> (?<comment>/\*.*?\*/) | (?<string>"(?:[^"\\]|\\.)*"|'(?:[^'\\]|\\.)*') </span><span class='regexp_end'>}mx</span></span><span class='period'>.</span><span class='id identifier rubyid_freeze'>freeze</span></pre></dd> <dt id="JS_LINE_COMMENT_REGEX-constant" class="">JS_LINE_COMMENT_REGEX = </dt> <dd><pre class="code"><span class='tstring'><span class='regexp_beg'>%r{</span><span class='tstring_content'>^[ \t]*//.*$</span><span class='regexp_end'>}</span></span><span class='period'>.</span><span class='id identifier rubyid_freeze'>freeze</span></pre></dd> <dt id="JS_BLOCK_COMMENT_REGEX-constant" class="">JS_BLOCK_COMMENT_REGEX = </dt> <dd><pre class="code"><span class='tstring'><span class='regexp_beg'>%r{</span><span class='tstring_content'>^[ \t]*/\*.*?\*/[ \t]*$</span><span class='regexp_end'>}m</span></span><span class='period'>.</span><span class='id identifier rubyid_freeze'>freeze</span></pre></dd> </dl> <h2> Class Method Summary <small><a href="#" class="summary_toggle">collapse</a></small> </h2> <ul class="summary"> <li class="public "> <span class="summary_signature"> <a href="#css-class_method" title="css (class method)">.<strong>css</strong>(css) ⇒ Object </a> </span> <span class="summary_desc"><div class='inline'><p>Conservative CSS minifier.</p></div></span> </li> <li class="public "> <span class="summary_signature"> <a href="#js-class_method" title="js (class method)">.<strong>js</strong>(js) ⇒ Object </a> </span> <span class="summary_desc"><div class='inline'><p>Ultra-conservative JS comment stripper.</p></div></span> </li> <li class="public "> <span class="summary_signature"> <a href="#minify-class_method" title="minify (class method)">.<strong>minify</strong>(html) ⇒ Object </a> </span> <span class="summary_desc"><div class='inline'></div></span> </li> </ul> <div id="class_method_details" class="method_details_list"> <h2>Class Method Details</h2> <div class="method_details first"> <h3 class="signature first" id="css-class_method"> .<strong>css</strong>(css) ⇒ <tt>Object</tt> </h3><div class="docstring"> <div class="discussion"> <p>Conservative CSS minifier.
