I'm not sure if there some configuration I'm missing, but I saw that #20350 was closed and so I'm submitting this more specific example. I have code that is trying to update the tree's opened list when something happens outside of the tree and it doesn't seem to work. This is an oversimplified example. It seems to work ok with an empty list, but not actual items in the treee.

items in data has been converted to a deep reactive proxy so items[0] in template isn't the original object.
