The legacy navigation was positioning baked TileMap navpolygons relative to the current Navigation2D node assuming that it is usually one of the parent nodes.
Without the deprecated Navigation2D node the default navigation map of the world_2d is used. This navigation map has no relative Node2D so it needs to use the global_transform of the TileMap to place navregions with the correct offset in case the TileMap is moved from the origin.
Backports features and bugfixes from current Godot 4.0 to 3.5 and brings functions and codebase of both version largely in sync to make tutorials more compatible and future backports easier.
