FontIconPicker closes when navigating to first or last page of icons

[oakesjosh]

The FontIconPicker modal closes when navigating to the first or last page of results. There's an open PR with a fix for this, but a new release has not been created for it.

Seems like forking the repo and merging this fix is our best bet since the PR was created over 2 years ago

Fix: fontIconPicker/react-fonticonpicker#25
Discussion: fontIconPicker/react-fonticonpicker#13

FontIconPicker is removed in 3.0
