Initially-hidden applet reports zero dimensions on startup using b12
When an APPLET tag is in a hidden SPAN/DIV tag which is then displayed dynamically after the page loads, the applet's getWidth() and getHeight() methods return 0.
This has consequences for applets that require the applet dimensions to implement double-buffering schemes, for example. The problem affects IE6 SP1, but not Firefox. The problem does not occur when using OBJECT/EMBED tags instead of the APPLET tag.
I've seen the problem in all the Update N builds I've tested, including b12. It did not arise in previous jre5 or 6 release versions. See attached basic applet and HTML file to test the problem.
