Issue description

Create two new layers in the Tilemap editor and exchange the order of the two layers. The corresponding editor displays no sorting.
Only by editing the TileMap view or reopening the scene will it be displayed correctly.

The problem comes from the fact Y-sorting is enabled on the TileMap node but not on any of the layer. This makes it so each layer is Y-sorted as a whole. Thus the system tries to Y-sort the layers which causes issues as they have the exact same position (more or less).

I added a warning in my local fork about that, but I guess I can PR it to master too.

问题来自于 TileMap 节点上启用了 Y 排序，但未在任何图层上启用。这使得每一层作为一个整体都是 Y 排序的。因此，系统尝试对导致问题的层进行 Y 排序，因为它们具有完全相同的位置（或多或少）。

我在我的本地分支中添加了一个关于这一点的警告，但我想我也可以通过 PR 来掌握它。

This problem still occurs when Y sorting is not enabled in TileMap。
