Flash cancels fullscreen mode when losing focus to another display

Using xubuntu 12.04. Related packages: flashplugin-installer, xfce (v4.10), google-chrome/firefox.

I work with multiple displays and frequently have flash videos full-screen on my secondary monitor. However, when the full-screen flash video loses focus to another window it cancels full-screen mode.

I understand this may be an issue that walks the line of working as intended making this possibly a feature request rather than a bug report. However, this functionality is available on other operating systems (Windows/OSX) and think it's the intuitive way for a flash player to function.

Note: fullscreen flash is currently bugged in chrome. The solution to which is to install flashplugin-installer and disable chromes default "pepper flash" plugin in chome://plugins (click details on the top right to see all versions of flash on system).
