Broken Tooltip Array Returns

[griffinlacek]

Currently returning an array from a tooltip callback will not show the array content, which are supposed to be their own lines for each index of the array. This functionality works with 2.1.4. Returning one string works as expected.

@griffinlacek I fixed this in #2776 and pushed a new release v2.1.6 that has this fix. My apologies for the inconvenience.

@griffinlacek I think in the tooltip an array gets reduced with a comma instead of showing multi-lines, is that possible?
