Issue description

I have basic setup of CharacterBody2D (player), RigidBody2D (box) and Tileset. When I hold arrow and push a box over a floor made of tiles then box can randomly stuck between tiles. Despite being random in nature bug is easily reproducible.

Notes:

• problem doesn't occur when using StaticBody2D as floor, even multiple joined together.
• problem doesn't occur when Lock rotation on RigidBody is disabled so probably there is some friction on the ground.

Steps to reproduce

Run the example project and hold right arrow to push box from the left to right, box will stuck in middle of tiles (added checkboard pattern for easier inspection).

For comparison, left side uses StaticBody as floor and pushing works correctly, even on junctions.

I think this is the same root issue, I wonder if example from here may be useful though - that is, if my example is reproducible on other machines as well - to be confirmed by someone.

I can reproduce the issue using your project, but the cause and the potential fix are already known. The main problem is implementing the fix properly.
