| <!-- |
| This test checks the interaction between prerendering and the Plugin Power Saver |
| feature. It expects: |
| - The plugin is not loaded during prerender. |
| - It is loaded (briefly) during the preroll of the plugin. |
| - It is replaced by the power saver placeholder after the preroll is over. |
| |
| This test relies on the Pepper plugin (but not the placeholder) implementing |
| the postMessage() function on the plugin object. |
