Core fields are not getting saved when using ajax block

patch #2 works well

Funny. This is absolutely critical, wondering why so few people commented here.

I'm going to contact the maintainer!

Please review the MR to get this fixed.

MR from patch #2 LGTM! Setting this RTBC.

Couldn't find any way to contact the maintainer!! So if anyone is able to, do it please and inform about this critical issue.

Notified him via Slack, but I contacted him recently regarding another issue and I got no feedback yet.
