It seems like the cause for the crash was that the maps in
`AnonymousAttributeInferencingResult` use node indices as keys.
However, the order of nodes changes when changing node selection.
Generally, we don't want to trigger a more expensive update just
because we changed the selection, therefore things got out of sync
when building the lazy-function graph.
The solution here is not a full fix. Other things that cause a depsgraph
update but don't cause a tree-update could still cause the same kind
of crash. A better solution would be to address the root cause which
is that trivial operations like selection changes node order which is
used in many places. Also see `BKE_ntree_update_tag_node_reordered`.
Disabling depsgraph updates when changing the active simulation
or repeat item is correct as well though, and it solves this specific crash.
