Hi there,
While trying to animation multiple SVG circle I found that interesting bug where if I rotate one of my circle (circle2) to the value -90 it seems to go back at to rotate back to 0deg at the end of my animation.
Fun fact, if you replace the value -90deg by -90.06deg it doesn't seems to bug, I would guess there is some rounding involve, it jumps to -91deg.
This bug seems to occur only on Safari 10.0.1
Even if I found a temporary fix for my problem I'm still curious on what could be done differently to avoid that bug
