Optimizely breaking Font Awesome Icon Picker within different Plugins

Hey,

i use different Plugins that use Font Awesome Icons, like Better Font Awesome or Shortcodes Ultimate.

These Plugins have inbuilt icon pickers, where i can choose the icon i want to use, for example to style a list or to insert a single icon in the text.

For some reason, when Optimizely is activated, these icon pickers do not work anymore. They do display the icons from which i can choose one, but when i do so, it does not use the chosen icon. Instead the icon name stays empty, as you can see in this screenshot of Shortcodes Ultimate (see “icon: “):

This happens with both plugins. For example with Better Font Awesome, the result looks like this: [icon name=”” class=”” unprefixed_class=””]

When i deactivate Optimizely, both icon picker in both plugins work fine again.

I have the latest Version of Optimizely installed ( 3.7.8 ).

I would be very glad, if you could help me fix this.

Thanks in Advance,

Norman
