The issue reported was that the recently introduced manual framerange of an action (see rB5d59b38605d6) was not having an immediate effect in case the action was pushed down from the Action Editor and only showed its effects after e.g. saving and reloading the file. However doing the same thing (pushing down the action) was working fine when done from the NLA. Now bring pushdown in sync (in terms of DEG update tagging) between the Action Editor and the NLA, meaning that now both the owner and the action are tagged when pushdown happens from the Action Editor as well.
