Increased to 1.8, because 1.5 still seemed overly close to the arrow.

opt nit: make it harder to break

  --md-arrow-width: 0.9em;
  -webkit-padding-end: calc(var(--md-arrow-width) * 1.8);
  background-size: var(--md-arrow-width);

[dpapad, 2016/10/07 19:14:04]

Done.

+        background: url(images/arrow_down.svg) 97% center no-repeat;
         background-size: 0.9em;
         border-bottom: 1px solid var(--paper-grey-300);
         border-left: none;
