Later implementation method will be modified to do save in pooled thread anyway.

commit documents to surely update injections when an editor action is about to be invoked (IDEA-CR-41724)

IDEA-204927 Please add a way to determine when the user has resized the components in a ThreeComponentsSplitter

Restore base action mechanism; create code completion handler correctly when action has been overridden

KeePass — nullize user name otherwise if empty value specified as CredentialAttributes it cannot be later retrieved

(because these stores combine several calls for better control/async instead of simple sequential delegation)

save settings - async flush on disk (part 2 - fix failing tests due to missed call to saveSettingsSavingComponentsAndCommitComponents)
