Webhelp output does not correctly display the 'DRAFT' watermark when used, because the pane has a white background.
The following CSS in webhelp-common.xsl appears to be the cause:
.ui-layout-pane { /* all 'panes' */ background: #FFF; border: 1px solid #BBB; padding: 05x; overflow: auto; }
Changing #FFF to transparent would fix this issue.

P.S. Perhaps the bigger question is why is this CSS hard-coded in the XSL instead of an external .css, such as positioning.css?
