How do I get rid of the yellow "Under Version Control" warning box?

I have a new install of Unity and Perforce, and when looking at the preview of graphic assets in Unity there is a yellow box with the message “Under Version Control” which covers up the size details of graphics in my Unity Project. This will go away once you check the asset out, but there are times that I’d like to see these size details without checking the assets out.

Does anyone know how to deactivate these yellow warning boxes?

Unfortunately, there is no way to close this notification without checking the file out at this moment.

We are making this notification closeable. When the change hits a release version I will let you know.
