Glazed Terracotta cannot be pulled by sticky pistons/ Or with blocks attached to slime blocks

While the update entails that the Glazed Terracotta cannot attach to slime blocks, this doesn't resolve the fact they cannot be pulled under any circumstances. They can be pushed, but not pulled. In the screenshot, the piston with the slime and wood plank should pull the terracotta, but the piston retracts as if the terracotta block was a immovable object. The lone terracotta in front of the sticky piston shown below cannot be pulled with it, but it can be pushed by a sticky piston.
