At the moment, the components in this library are not working in IE11 when transpiled with Babel (eg. in this demo).
The probable cause is that Babel (required for Svelte compatibility with IE11) is skipping transpiling the Mapbox JS file because it's very large. The fact that it is coded as an ES6 module (see issue #1 ) then means that it is not running on IE.
