Slider ticksLabels do not line up with ticks

[ryanrishi]

If I want to render a slider that goes from -100% → 0% → 200%, I pass in the following. Doing so results in a slider that looks correct, but the ticksLabels are not aligned with the ticks.

{{ui-slider
  value=value
  min=-100
  max=200
  ticks="-100, 0, 200"
  ticksLabels="-100%, 0%, 200%"}}

Here is a twiddle reproducing the issue.
