Fix slow appearance of nodes on tree view

The tree view rendering performance is optimized by improving the node
render queue ordering. The node rendering order is modified based on the
expansion state and the depth in the hierarchy, leading to faster
rendering of visible nodes. This optimization is applied when the tree
nodes are not expanded to improve the rendering speed.

This new ordering ensures that nodes are rendered more efficiently,
prioritizing nodes that are collapsed and are at a higher level in the
hierarchy.
