noink doesn't disable ripple for first click

[blasten]

Moved from PolymerElements/paper-slider#105

If I add the noink attribute, I still get a ripple effect for the first click, though I don't subsequent clicks (maybe - it seems like there is a situation where the ripple effect also occurs after the first one).

Any ideas?

Reproducible on:

1. https://elements.polymer-project.org/elements/paper-checkbox?view=demo:demo/index.html&active=paper-checkbox

and

@notwaldorf
noink does create paper-ripple on demand when it is expecting to be not to create any ripple.
Is this a bug or an expected behavior that noink only hides the ripple effect but the paper-ripple will be created no matter what?

It still creates a paper-ripple since a ripple will show on focus (even if noink is set, which only affects mouse/touch)

@keanulee It makes sense. Thanks for pointing out.

@notwaldorf FYI: re-focusing browser tab causes ink to appear event if noink attribute is set.

Reproducible on https://elements.polymer-project.org/elements/paper-checkbox?view=demo:demo/index.html&active=paper-checkbox

Steps to reproduce:

1. Toggle checkbox from second demo snippet (which has noink)
2. Switch to other browser tab
3. Go back to previous tab, you'll see the ripple around the checkbox.

Same for paper-toggle-button, paper-radio-button etc.

Is it by design? Shall I open another issue?
