Quick type end/home key before intelliSense pop up will unintentionally switch to first/last document ?

When I type some word, before the resharper IntelliSense pop up ,then very quickly hit the end key, then the visual studio will switch the current document to the last visible tab.

But when I use visual studio native IntelliSense,this issue will not happen.

Is anyone experienced this problem? 

I searched Google, but find nothing about this topic.
