I am not sure if this will work better or not. Currently, updates do not work well -- as in, user clicks "close" on notification, page reloadds as intended, but the version may not be updated unless this is done 2 or 3 times.
This issue did not exist when we used the modal -- ref diff D15521. However, I can't determine any core logic changed in that diff.
Potential fix here. If it doesn't work, will revert. But what we currently have doesn't work well either.
