Polyline with duplicate coordinate at the end not rendered correctly

[jaapster]

See this example.

A polygon is not always rendered correctly when the last two coordinates are identical.
In the example, when you remove the last coordinate the polygon is rendered correctly.

The last two coordinates of your polygon are identical, if you remove one of them, the polygon renders correctly.

@kkaefer that's in the description. :)
@jaapster the behavior is indeed weird. Also noting that a similar bug happens if you change the type to MultiLineString, meaning that it's not about polygons.

@mourner For good measure I tried the coordinates with type "LineString. That yields a similar result although the "gap" is positioned slightly differently.

Not a GeoJSON-VT issue. Looking into the GL line tesselation code now...

Fixed in #4634

Thanks @mourner!
