has been reported blender/blender#37473, #28286.

Would be good to note this in RNA docs though.

As noted by Campbell, this is a known problem :(

Unfortunately, we cannot enable this for all properties - last time we did, people were getting random crashes when trying to load their scene files (with lots of compo nodes), as most of those things end up doing some crazy things (e.g. immediately force recalc right then and there) in their update callbacks.
