Although this works by itself, it should actually happen after:
"Reshuffle collections base flags evaluation, make it so object is gathering
its base flags from collections."
Meanwhile we have one single hacky function (deg_flush_base_flags_and_settings)
to be removed once the task above is tackled.
Note: The logic for "SETS" here is working, but SETS themselves seem to be broken in 2.8.
Note 2: ID Nodes (or IDs) should be tagged properly, so we can skip the ones that were not
added directly by the current scene layer.
