No need for the word "pixel" in this comment.

Done.

+     * @param isFirstSuggestionAHint If true, the first suggestion is a nin-fillable hint.

[please use gerrit instead, 2017/05/15 14:37:29]

non-fillable

[csashi, 2017/05/15 20:07:26]

I removed this as a constructor parameter because we show "CLEAR FORM" when form
is filled.

+     * If {@param animationDurationMillis} > 0, we reverse animation to scroll the first
+     * suggestion out of the viewport at the end of the reversed animation.
