Title: Fix for issue #233

When a video preview is played, and then the post is hidden, the video continues to play because the `div.expando` contents are not emptied. See [issue #233](https://github.com/reddit/reddit/issues/233) for discussion.

This patch fixes the this issue by calling the pre-existing logic that is called when a post is collapsed.
