I just noticed an interesting bug with minifying local fonts. I have a small iconset from Icomoon, which I use with the with the Notepad theme as replacements for the defaults (in the footer). I serve this through local css (unminified, at the top), in its embedded form, but the font does not render when minfication (and pipelining) is enabled in Grav.
Here’s an Image, and the live site (see bottom for footer). Any thoughts on why the font does not render when minified?
I queue custom.css from base.html.twig (inherent to the theme), like so: {% do assets.addCss('theme://css/custom.css') %}. This custom css is the same as the local css linked above. Basically embedded and the inclusion of icomoon.eot.
