paper ripple and select bar don't respect border-radius

[ebidel]

Setting <paper-tabs style="border-radius:30px;> gives me this:

But the ripple and select bar overflow the border-radius clipping:

Still present unfortunately in the demo page: http://webmup.com/3rr9S/vid.webm...

You can also see in the clip odd clipping behaviour for the tab select bar after the ripple has faded out :/

Not specific to paper-tabs - opened an issue with paper-ripple: googlearchive/paper-ripple#28

This can achieve by css, see code below,

<dom-module id="app-index">
    <style is="custom-style">
        :root{
            --my-custom-color: #ffb6c1;
            --paper-tab-ink: var(--my-custom-color);
        }
        paper-tabs{
            {
                --paper-tabs:{
                    background-color: pink;
                    border-radius: 100px;
                    color: white;
                }
            };
            {
                --my-ripple-color: pink;
                --paper-tab-ink: var(--my-ripple-color);
            }
        }

        paper-tab.iron-selected {

            background-color: white;
            border-radius: 100px;
        }
