The issue was caused by dependency graph always ignoring animation update when it is first time constructed. This was a way to make it preserve unkeyed changes on undo/redo. This, however, made it so changes of animation data itself (such as deleting/moving keyframes) did not trigger animation update by the dependency graph. This worked prior to copy-on-write because animation recalc flags were stored in the DNA and never re-set on file/undo load. This was giving dependency graph a clue that animation is to be re-evaluated when operator explicitly asked to (more precisely, when such operator was undone/redone). This change makes it so original ID's recalc flags are storing recalc flags when ID is tagged for update as an response to user input. This way re-building dependency graph can force animation to be updated on redo. Tricky part here is that ID's recalc flag is no longer to be zeroed when loading undo step (which is the same as reading .blend file). This is something what works differently comparing to legacy dependency graph, which was zeroing object's recalc flags there but not animation data's recalc flags. Shouldn't be causing issues, since unkeyed changes are not preserved upon opening a file anyway, at least to my knowledge.
