	3 This test checks the interaction between prerendering and the Plugin Power Saver

	4 feature. It expects:

	5 - The plugin is not loaded during prerender.

	6 - It is loaded (briefly) during the preroll of the plugin.

	7 - It is replaced by the power saver placeholder after the preroll is over.

	8

	9 This test relies on the Pepper plugin (but not the placeholder) implementing

	10 the postMessage() function on the plugin object.
