It seems that the 'shake' option of the scroll-to behavior is unaffected by Timescale (If timescale is set to 0, the shaking continues)
I am not sure if this is intentional but it seems not so to me.

You're right, the timescale only affects the duration of the shake, not the actual shake. I'll try get this sorted for a future build.
