same comment as #1414 (comment) - is this an intentional pattern now?

Yes, much better to my eye - thanks!

var opts = _convert(Lib.extendFlat({}, base, {
mode: 'lines',
lon: [10, '20', 30, 20, null, 20, 10, null],
lat: [20, 20, '10', null, 10, 10, 20, null]
}));

assertVisibility(opts, ['none', 'visible', 'none', 'none']);

var lineCoords = [
[[10, 20], [20, 20], [30, 10]],
[[20, 10], [10, 20]]
];

Previously, this was:

var lineCoords = [
  [[10, 20], [20, 20], [30, 10]],
  [[20, 10], [10, 20]].
  []
];

which lead to an invalid GeoJSON and made mapbox-gl fail.

Great. I thought this would be a pretty easy fix. Just to confirm, I assume it will also handle [10, '20', 30, 20, null, 20, 10, null, null] without problems?

Yes it does: 1a22beb
