iCloud Keychain out of sync after Mac user password change on my macOS Mojave 10.14.5 (18F132), where I'm logged in with my iCloud account, if I perform a domain Mac user password change (from System Preferences) then the iCloud Keychain sync will be turned off. If I go to iCloud prefs I can re-enable iCloud Keychain, but it won't sync anymore with the ones I've on my iDevices.

Any hint about it? 

Thank you
Probably I found an acceptable workaround: 


disable the iCloud Keychain (keeping a local copy)
change password, 
log out and log in again into your User account
re-enable the iCloud Keychain


It seems to work with any need to log out from iCloud and/or loose data.
