RigidBody2D PhysicsMaterials not applied if collision_mask or collision_layer is changed

[TrevorPeyton]

Describe the bug

PhysicsMaterials applied to bodies through the physics_material_override are not applied if they are created before assigning a collision_mask or collision_layer. They work properly if they are defined after setting collision_mask or collision_layer.

To Reproduce

Define the physics_material_override in code like such:

physics_material_override = PhysicsMaterial.new()
physics_material_override.bounce = 0.0
physics_material_override.friction = 1.0

then set the collision_mask or collision_layer property to anything:

collision_layer = 1
collision_mask = 1

and the materials are now ignored.

Expected behavior

Regardless of when the PhysicsMaterial is defined in code, the body should reflect it. If collision_layer or collision_mask is updated it shouldn't have any bearing on the material.

Environment:

• OS: Mac
• Version: v0.8.8
• Godot Version: 4.3
• 2d (fast and slow)
