Physics glitches if you flip a layer. Dangle property will glitch on layer with -100% "scale x". pls fix

To reproduce issue:

• create head with dangle property on ears
• add transform property to head
• in scene, create hold keyframes of 100% and -100% on head “scale x” to flip head as needed
• when head is flipped -100% “scale x” the ears with the dangle property will start glitching 

I’d love to be able to flip layers for head turns etc. in character animator without losing physics, thank you.
