Steps to reproduce:

1. Add a Site 'newSite'
2. Add a page to newSite, 'newPage'
3. Add a WC article to each Liferay, newSite, and Global site scopes
4. Add an AP portlet to newPage
5. In AP Configuration, add the Global scope, and remove newPage scope > Save
6. Still in AP Configuration, click Select > Other Site...
   • Choose Liferay
7. Click Select > Other Site...
   • Choose newSite

Expected result:
User will be able to add any sites available to the site scoping iframe.

Actual result:
User can only add one Site, then the second site seems to work when clicking 'Choose' - but the configuration page doesn't refresh, and clicking back into the site scope iframe, the user will find the scope is unavailable. See screen record.
