Cannot preview KML files under the upgraded JS libs

[u10313335]

ckanext-geoview version

0.2.0

Describe the bug

The KML files cannot be previewed.

Steps to reproduce

1. Upload a KML file, such as https://github.com/mapbox/Simple-KML/blob/master/sample/example.kml.
2. Open the resource page.

Expected behavior

The KML file can be previewed in the v0.1.0:
