Proess fails after icon upload

[BernhardBehrendt]

When building an iconset the process seems to "freeze".

Commandline output:

[icomoon-cli] Started a new chrome instance, going to load icomoon.io.
[icomoon-cli] Dashboard is visible, going to upload config file
[icomoon-cli] Selection icons is empty, going to create an empty set
[icomoon-cli] Uploaded config, going to upload new icon files
Error: Node is either not visible or not an HTMLElement
