On the channel list (on the left), when one hovers the mouse over a channel information pops up in the page. This hover state almost always gets stuck open, even when the mouse remains in the browser window.

The pop-up will remain permanently open over the Channel creators video content.

What should happen: When hovering the mouse over a channel the channel pop-up should be shown. When the mouse leaves that channel the pop-up should always disappear.

The hover state should close on several events, including:
- when the mouse leaves the browser window
- mouse moves away from the channel hover area.
- mouse moves over Titles and link in the left column (example: "Show More", "Live Channels", "Recommended Categories", "Show Less", "For You", "Followed Channels") and any white-space in the left column that is not a channel
