Tree grid - sorting of deep records

[Jelnes]

In the tree grid, something unexpected seem to happen to the order of records on deeper levels.

In the example the tree grid and the grid is provided with the exact same data, but the records do not keep their order within their levels:

Is this a bug or is there some configuration I must do on the grid? I know I can use the sorting interface of the grid to handle this manually, but that might come with other side effects in my application. It also seems a bit counter intuitive that the order of the data is not preserved among siblings.

@Jelnes Thank you for your feedback regarding the unpredictable ordering of child records within the tree structure.

We've confirmed this is a fault in our hierarchy building logic where the single-pass construction fails to guarantee that children are pushed to their parent's array in the original data order.

The fix involves refactoring the logic into a two-pass construction to ensure complete map population before linking. We anticipate that this change will be finalized and deployed within the next two weeks.
