script blocks in document header are not processed

Original author: OneWinge...@gmail.com (December 15, 2011 00:25:19)

What steps will reproduce the problem?

1. Pass the inner-HTML of the body of an HTML document with a <script type=text/php> tag inside it; or, alternatively, with the script inside the head-section (http://www.w3schools.com/tags/tag_head.asp).
2. Pass the above to render.

What is the expected output? What do you see instead?
Expected the script, in this case a header as per FAQ examples, to execute and draw the header; results: PDF produced as normal, but w/o the script executing.

What version of the product are you using? On what operating system?
OS: Linux 2.6.35.14-96.fc14.i686 / GNOME 2.32.0
DOMPDF: 0.6.0 beta2

Please provide the HTML source code you want to convert, or any additional
information.

Start at the render entry point described in the reproduction and trace how script tags are handled in the document head versus the body. Use the supplied text/php header example to verify that the script executes and draws the header in the generated PDF.
