'viewselected_exec()' [which uses evaluated view layer] would query
BASE_SELECTED flag, but it was not set on base_eval, but on its
base_orig.
reason for this is 'ed_object_select_pick()' would modify base flags
[through 'ED_object_base_select()'], but not tag scene
ID_RECALC_BASE_FLAGS.
thx @sergey for hinting.
