Compact attribution control does not show in IE11

[gingemonster]

If you set a map as follows:

var map = L.mapbox.map('map', 'mapbox.streets', {attributionControl:{compact: true} })
.setView([40, -74.50], 9);

To show a compact attribution control then the "i" icon in the bottom right is not visible at all. Seems to be something to do with the :after style not getting priority in IE

Thanks for your report @gingemonster !

Thanks to @danswick for 🕵️ – this seems to be caused by an IE bug where descendants an invisible element are also made to be invisible 😞
