Hi,

I notice that when a treeitem have a lot of children, when open it the first time it takes too long.
I reproduce it here:
Example

Try to open "1". The first time it is opened it takes too long. Next times timing is OK.

I know it is a long example but I wanted to reproduce exactly the number of treeitems I have in a real case.

Can it be solved?

Thank you!
