 I'm afraid this preg_replace() is not "up for the job". As mentioned in
 the comments at the link you posted, it will potentially break anything in
 a `<script>`, `<pre>` and `<textarea>` tags. There are probably better
 "HTML white space removers" you could use.

 Of course we will fix the comment style in this inline JS, but you will
 probably run into more problems in the future.
