Set release status flags based on info from the regressing bug 1705676

I just landed a fix for bug 1785018 which I believe should fix this as well.
Note that bug 1705676 is only enabled on Nightly + Windows, so this performance regression is not being shipped to the user.
Leaving ni? to check back in a few days.
