Second frame on welcome screen sometimes appears repeating milestone resources

While discussing NEXUS-7811, Jason noticed the screen I took had a second frame repeating the milestone resources available for admin on the welcome page.
I was able to reproduce this but not consistently by logging in and out of the system as admin (deployment and anonymous do not have these resources at this time).

Since I was able to repro several times despite not every time I am filing.
If I see further tidbits about this I will add.

I am making this minor because once this frame shows up, it remains even on logout, exposing these resources to a non-admin.
I also have noticed less frequently while testing this that the resources sometimes stay on the page on logout (but on the non-second framed screen). I mulled filing a second ticket but was unable to repro this behavior in FF or Chrome, so I'm holding off for now, semi-hopeful this ticket fix may cleanup that as well.

I did not specifically check NX2 for this at this time, however, I've never seen this there before.
