As an optimization, dependency graph evaluation skips through no-op nodes at the scheduling stage. However, that leaves update flags enabled on the node, and the most problematic one is the USER_MODIFIED flag, which get flushed to children every time the no-op node is tagged. This in turn can cause simulation caches downstream to be permanently stuck in an outdated state until the depsgraph is rebuilt and the stuck flag cleared out.
