WebApi global action filter executing twice

[abpatel]

I'm noticing that after installing this package, the OnActionExecuting and OnActionExecuted methods of my custom action filter are being invoked twice.My filter happens to be a Global filter and I noticed that this happens only if the custom action filter does not have the [AttributeUsage] attribute.

Before installing this package, I was using the NinjectScope and NinjectResover as indicated below and the filter behaved as expected without the [AttributeUsage] attribute.

Just wanted to get some clarity on whether this qualifies as a bug or is there some inherent behavior that I'm unaware of.
