PinJoint2D glitches out since the 4.7 update: Node B is stuttering when moving Node A #122480

Tested versions

System information

Godot v4.7.1.stable - Windows 11 (build 26200) - Multi-window, 1 monitor - OpenGL 3 (Compatibility) - NVIDIA GeForce RTX 4080 (NVIDIA; 32.0.16.1088) - AMD Ryzen 5 5600X 6-Core Processor (12 threads) - 31.92 GiB memory - WASAPI (48000 Hz, Surround 5.1)

Issue description

I have a CharacterBody2D (Node A) and a RigidBody2d (Node B) joined together with a PinJoint2D. Node B followed Node A as expected up until 4.7 update come out. Since the update when I move Node A (my player character) Node B stutters, or "teleports ahead" as can be seen in the following comparison video:

Steps to reproduce

I've added an MRP with the simplest setup I could think of. Just move the character with the left/right arrows and the issue should occur.

Minimal reproduction project (MRP)

I tried setting the softness, turned off sleep, etc. but nothing seems to solve this. I also searched for PinJoint2D-related updates but found nothing so this must be a deeper physics issue maybe introduced in the 4.7 update?
