Attached a Quicktime File, Playback Takes Over Whole Window Follow

Attached a mov file to a ticket. It was a screencast made using the built in ability of Quicktime in Mavericks. The attachment was 7MB and went up ok. When you click on it, it takes over the whole window and only part of the screen that was captured shows in the window.

Expected: that it would appear in some kind of player or a popup window if not.
