Performance issues with large amounts of nodes

[gruberroland]

Describe the bug
When expanding a node that has a large set of subnodes then it takes very long to load.

To Reproduce
Create a node with 10,000 subnodes and try to expand it.

Expected behavior
Optimize code to reduce the loading time.

Desktop (please complete the following information):

• OS: Linux
• Browser Firefox, Chromium

Additional context

Line 6265 in c02a435

this.resizeObserver = new ResizeObserver((entries) => {

This example has about 100.000 nodes and expands fast (click this button: ).
Maybe try giving the tree div a fixed size. Can you share some example code to reproduce it?
