Version

1.7.0 - Breaking changes around the minimum Office UI Fabric version require that we use 1.7.0 for SP 2016 On Premise support (RE: #149)

Expected / Desired Behavior / Question

The Taxonomy Picker browse panel (tree view) should be work with SP 2016 on premise

Observed Behavior

The following issues are observed when attempting to use the Taxonomy Picker in an on premise environment.

• Clicking either Save or Cancel button (in the tree view) causes the spinner to appear and the panel "freezes" and remains open, unable to close via the panel close button, unable to cancel via the cancel button
• if allowMultipleSelections is enabled, the same behavior as above is observed. In addition, the following error is reported every time a term is selected:

sp-webpart-workbench-assembly_en-us.js?version=1:174 Uncaught TypeError: sp_lodash_subset_1.uniqBy is not a function
    at TaxonomyPicker.termsChanged (TaxonomyPicker.tsx:176)

1. Clone the repo at https://github.com/cameronsibbald/spfx-controls-react
2. Load the TestTaxonomyPicker web part into the workbench of a SP 2016 on premise environment
3. Enter a valid term set id for your environment into the text box
4. Click the "browse" icon to the right of the Taxonomy Picker field to open the browse panel (tree view)
5. Attempt to Save or Cancel
