State: open

1. Tab A go to https://preview.nuget.org/packages/upload
2. Tab B go to https://preview.nuget.org/packages/upload
3. Tab A, upload a package, don't verify/cancel
4. Tab B, Upload a package

Blank page with text :

"The page was not displayed because there was a conflict."

Low pri but the blank page is not so nice, could just redirect to the first package to finish.
