is_active_widget() should skip orphaned widgets

[Ninos Ego]

The function is_active_widget() should also skip orphaned widgets. Orphaned widgets are also inactive widgets.

Yeah, this makes sense. Minor points: we should use triple-equals, and substr as used elsewhere to check for orphaned_widgets:

( 'wp_inactive_widgets' === $sidebar || 'orphaned_widgets' === substr( $sidebar, 0, 16 ) )

Why was the severity changed to major?

[Ninos Ego]

substr instead of strpos

[Ninos Ego]

Sry because of the severity, it was a mistake. I've uploaded the ne patch. Should be ok now.
