Perhaps getPath() should just return `Vector<Ref<ContainerNode>>` instead, and change this into something along the lines of:
```
while (!startTopDownPath.isEmpty() && startTopDownPath.last()->hasOneChild())
    nodesToRemove.add(startTopDownPath.takeLast());
```

I tried this and found we need to make changes to updateInsertions(), which seems unnecessary for fixing the bug. I can do this in a follow-up patch, as getPath should only return ContainerNodes.
