Shape Layer stroke repeater with animated scale bug.

Steps to reproduce:
    1. ...Elipse path on shape layer 

2. Add repeater 

3. Add stroke after repeater

4. Repeat 10 circles

5. Animate scale of repeater 100 to 600%

Result: ...

At high percentages the stroke breaks and starts to do weird things. It works ok if the stroke is applied before the repeater but that scales the stroke and thats not really the effect I'm going for. 

Expected: ...

Strokes to animate normally and not black out and/or stroke in weird unpredictable ways.
