Command-~/Exposé to another window while <video> is in full screen, breaks Safari, eventually leading to crash

• Component: WebKit Misc.
• Status: RESOLVED FIXED

[Jer Noble]

Using Command-~ or Exposé to switch to another Safari window while a <video> element is in full screen mode results in broken behavior: contentless windows, mispositioned full-screen window, and ultimately crashing when closing windows.

This doesn’t follow our usual style of putting the * in the traditional place for Objective-C classes.

Extra space here after period. Misspelling of suppress.

> +        NSWindow* webWindow = [[self webView] window];

Same style issue here.

> Source/WebKit/mac/WebView/WebFullScreenController.mm:533
> +        // In Lion, NSWindow will animate into and out of orderOut operations.  Supress that

Same mistakes here.

Same issue again.
