When backporting JDK-8180064 to FX 8u-dev, a closing comment for the copyright header was inadvertently omitted in cssref.html, which is part of the javadoc bundle. This causes the entire first half of that HTML page to be skipped and the remaining of the document to be badly rendered. This bug is in 8u152, and now also present in 8u161 and 8u162 EA builds.
