To clarify: While the nodes retain their "selected" status visually, their keys are removed from the selected v-model. So visual representation and actual selection are out of sync.

This is a tricky one. Because the expected behavior that you describe is not what will happen when this bug is fixed. Since the filtering is happening outside of the component, it has no way of knowing that previously selected items that are filtered out are supposed to 'stay' in the selected set, and return when you reset the filter.

All it knows is that it is given a new set of items, and it creates the tree from that, resetting state in the process.

I do get what you're trying to achieve, but I don't see an immediate easy solution, other than internalizing a filter function in the component..

I might have a solution in mind, not sure if this helps or not.
I suggest to have a scoped slot where a node can be hidden (not removed) based on on an item property. However, this does create a problem, what if the node hidden is a parent node, in this case the node children should be hidden as well.
Just an idea I suppose.
