paper-date-picker-item.html uses the following import:
<link rel="import" href="../paper-styles/paper-styles.html">
This causes iron-flex-layout/classes/* to be imported, that contains deprecated things. such as /deep/
An easy fix is to replace
<link rel="import" href="../paper-styles/paper-styles.html">
with:
<link rel="import" href="../iron-flex-layout/iron-flex-layout-classes.html">
and
<paper-ripple fit></paper-ripple>
with
<paper-ripple class="fit"></paper-ripple>
Because from what I could see, only "fit" was being used.
It removes deprecation warnings and makes it a bit more future proof.
