Otherwise it blinks. Patch to follow. helpScreen.css is only 150 lines, with primitive selectors only.

You could fix this by listening for the load event on the link element and aiting to show the help element until it is loaded.
(In reply to comment #2) > You could fix this by listening for the load event on the link element and aiting to show the help element until it is loaded. I am thinking of iframe-ifying parts of the inspector (i.e. hosting TextViewer in iframe as originally was with SourceFrame, hosting network log in iframe, maybe help screen). The rationale is that number of the css rules multiplied by the size of the dom makes us render slowly. Localized doms with localized styles will be a better fit...
