Description
In IE 10/Edge, there appears to be a browser security issue with the tl-icons font when the Timeline is loaded over HTTPS. This is true whether the timeline is embedded "directly" using same-source JS or in an iframe (i.e. it is not just a cross-origin issues).
I discovered this with my own timeline, which is not public, but it is reproduced in your example here: https://timeline.knightlab.com/examples/houston/index.html
The result is that the previous/next icons on the slide navigation do not display. This is not very user-friendly especially since the accompanying text is by default not very legible unless hovering.
It would be preferable to have a visible fallback if possible.

Research direction
Reproduce the missing tl-icons font in IE 10/Edge by opening the Houston example over HTTPS, testing both direct embedding and an iframe. Trace how the slide navigation icons are loaded, then verify that the previous/next controls display either the icons or a visible fallback.
