Bug preventing plugin to work on High Sierra
Normally I wouldn't bother to post a bug report for OS' that's in beta, but since we're on beta7, which means we probably have just one beta left before it goes Gold Master. Also from what I know Sketch has patched issues for HS, which means that the bug preventing iconfont to work seems to be laying on the plugin's side.

Basically what happens is when I trigger **Grid Insert**, the window that should appear just doesn't. I believe it's there, invisible or 0x0, because the Sketch window is blocked until I hit ESC to close the invisible Grid Insert picker.

If there's a way I can debug or provide more info please let me know.

This plugin is essential for me to work on @jsfiddle UI, so I'll help as much as I can to get it working again on HS.
