@Mic92 could we backport the first commit (15e4447) to stable?
(not sure if non patch update ok to backport?)

I would delegate this decision to @fpletz or @globin
Update chanes does not look trivial to me and the 7.7.x branch seems to be still supported:

I guess a newer patch release of it could be backported

I will backport the first commit.
