Lua: Inconsistent behavior with actors affected by Disable and SetDelete commands

Actors that affected by Disable command:

• Can run mwscript
• Can't run lua scripts
• Immediately invalid in Lua, except when you disable object before savegame, then on game load and cell change they becomes valid again
• Always trigger onActorInactive
• Sometimes trigger onActorActive during game load

Actors that affected by SetDelete command:

• Can't run mwscript
• Can run lua scripts
• Becomes invalid in lua on cell change. Become valid again when you return to original cell

I expected that MWScript and Lua will work on disabled objects, and won't work on deleted objects
