Errors are not being displayed correctly when comparing field values

At the moment it seems that errors are not being displayed appropriately all the time. This can be seen when using the comparison validation.

This can be seen on the tutorial page of the demo site in the compare validation section. Warnings are only being displayed on focus and do not persist.

I've made some updates to improve the stability of warning messages but won't close this yet until I'm sure that the problems have been resolved.
