Contour geojson layers disappear at high zoom

[stefmarais]

Version: 0.52.0

I have a geojson representing contours of interpolated weather data. Certain portions of the contour layer disappear at higher zoom levels as seen in following screengrab:

Using the same geojson file on http://geojson.io shows the expected outcome (See below), with all contours visible at all zoom levels.

Issue is replicated in the following Fiddle:

I want all contours to be present all the time, regardless of the zoom level. How can I fix this?
