CompositeCollider2D.GenerateGeometry does not regenerate Collider when the composite is TilemapCollider2D

Physics2D

-

How to reproduce:
1. Open up my attached project
2. Add Playground Scene into Hierarchy and Enter Play Mode
3. Observe the Collider behaviour

Expected result: GenerateGeometry() updates the newly created Tiles Collider geometry and the blue falling block collides with the Tiles
Actual result: GenerateGeometry() does nothing when used in this context, a blue block falls down through the white Tiles and hits the red block down below

Reproduced in: 2017.4.39f1, 2018.4.21f1, 2019.3.9f1, 2020.1.0b5, 2020.2.0a7

    Resolution Note (fix version 2019.3):

    Fixed in 2020.2.0a12.1461_72e8467d6ce5

    2D: Added: Add HasTilemapChanges and ProcessTilemapChanges for TilemapCollider2D to immediately process Tilemap changes instead of waiting for batched processing in LateUpdate.

    New functionality code example:

    private Tilemap tilemap;
    if (tilemap.GetComponent<TilemapCollider2D>().HasTilemapChanges())
    {
    tilemap.GetComponent<TilemapCollider2D>().ProcessTilemapChanges();
    }
    tilemap.GetComponent<CompositeCollider2D>().GenerateGeometry();
