Since {rB46aa70cb486d}, using `NC_SPACE | ND_SPACE_VIEW3D` as notifier is restricted to space data as a reference. This was still used though for RNA updates in other places (namely `rna_camera`, `rna_scene`, `rna_animviz`), and passing NULL would automatically set the notifier reference to the owner id. Above commit would happily filter these out, leading to missing refreshes. Now use more specific notifiers (in case of animviz a new `ND_DRAW_ANIMVIZ` was added). This was reported for Camera background images btw. Fixes T86670. Maniphest Tasks: T86670 Differential Revision: https://developer.blender.org/D10758
