Description:
I'm seeing this in Echo because it automatically sets new preferences different to the defaults but the same behavior might be present elsewhere.
Tested on mediawiki.org and test.wikipedia.org
I cannot reproduce it on my dev install that does not have production style caching and replication
To replicate:
create a new user.
immediately go to Special:Preferences#mw-prefsection-echo
note what preferences are set
A new user should have most email turned on, but I see most email turned off as is default for existing users.
Refresh the page and the correct values are shown.
It could be a caching anomaly, but the code looks fine to me.
It could be replication lag between the master DB that the settings are saved to and the slave DB that they are loaded from.
If it stays as a 5 second lag, it is an edge case that only affects me testing that default preferences are being set. If the lag varies it could affect real users sometimes.
