Describe the bug
Automatic tree layout child nodes in wrong order.

To Reproduce
Steps to reproduce the behavior:

1. Go to 'layout'
2. Click on 'tree layout'
3. Automatic tree layout child nodes in wrong orderr

Expected behavior
When I set up automatic tree layout, the first-level child nodes behind the root node are not arranged in the order I placed them. How do I set this up?

hi, thank you for your answer.

I set up the nodes following this method, but the order still doesn't change. For example: the order of first-level child nodes from top to bottom is 1, 2, 3, 4, 5, 6. After applying automatic horizontal tree layout, the node order becomes 4, 5, 6, 1, 2.

After a long period of debugging, I finally found the cause of the problem.

The ordering rules of child nodes in automatic tree layout are based on the creation time of the child node connecting lines. If I modify the properties of a sub-node connection line (for example: constraint direction, front and back position in graphics options), the creation time (sequence) of the connection line (sub-node) will be disrupted. If you reapply automatic tree layout at this time, the order of the child nodes will change to the order after changing the connection line properties.

I think this layout rule method is unreasonable, the user experience is very bad, and there are no relevant instructions in the user manual document. The sorting of child nodes in automatic layout is best sorted according to the xy coordinates of the child nodes.

The alternative I've found so far is to delete all related connecting lines and create new connecting lines for each related child node in the new order.

I'm a beginner in drawio and don't know if there is a better solution. If anyone has a better solution, I would be very grateful.
