Fullscreen video HUD stays on top when switching to another window (e.g. via Alt-Tab)

• Component: Media
• Status: RESOLVED FIXED

[Adam Roben (:aroben)]

To reproduce:

1. Go to a page with <video controls>
2. Click the fullscreen button in the video's controls
3. Switch to another window via Alt-Tab (e.g., the Safari window that contained the <video>)

The fullscreen video's HUD stays on screen, on top of whatever window you've just switched to.

After this, I think you should assert that m_hudWindow is non-null. And maybe you should bail if it is null, in release builds.
