Arrow keydown not updating selected node in Tree with a lot of nodes (300+)

Hi there Webix team! I am having an issue using the up and down arrow keys to select nodes in a Tree.

If I hold down one of the arrow keys, I would expect the selected node to quickly scroll through the tree. This works exactly as expected for trees with a small amount of nodes. However, when the Tree gets large enough, the selection update seems laggy and will only happen occasionally (about 200-300+ nodes seems to be where it begins to fail). I can try to provide more information + a video if needed.

I have tried numerous approaches to try and solve this issue on my end, but to no avail. Any help is greatly appreciated!

Unfortunately, I wasn’t able to reproduce your issue.

Some more information and description would be really helpful!
