As user scenario, user logged twice, first time as keycloak user and the second time as FB user to provide auth to keycloak. And i`m, as user, remember, that i`m logged into FB. In case when sync keycloak logout with social I will be surprised, If opening FB see login page again. Also, I can working with keycloak secured app and FB at the same time ( ex. serfing news on FB ) and It will be bad, if FB-site logout when I logout from keycloak.

Both options are quite bad imo. But likely better to prefer security over usability...
Btv. It looks that currently we never propagate Keycloak logout to Facebook. And probably it's same for other social networks.
