| +<!-- |
| +This test checks the interaction between prerender 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 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. |

Use getElementById? Named properties on the docume

Use `===` maybe? `==` can have some weird effects

This is the new test 'repros' the old problem and
|
| + var plugin = window.document['plugin']; |
| + function handleEvent(event) { |
| + // We should eventually get a message indicating that the plugin has been |
| + // throttled and replaced with a static placeholder. |
| + if (event.data.isThrottled) { |
| + plugin.removeEventListener('message', handleEvent); |
| + window.domAutomationController.send(plugin.postMessage == undefined); |
| + } |
| + } |
| + |
| + // The plugin should (briefly) exist for the preroll phase. |
| + if (plugin.postMessage == undefined) { |
| + window.domAutomationController.send(false); |
| + } |
| + |
| + plugin.addEventListener('message', handleEvent); |
| + plugin.postMessage('getPowerSaverStatus'); |
