In a multi-repository configuration, 'select2' widget in 'Import' popup only suggests folders from domain 'default-domain'

How to reproduce:

• configure a multi-repository configuration as described in documentation Multiple+Repositories+Configuration (see attached ZIP file for a sample configuration template)
• navigate to the second repository
• click on button Import to import a document
• type characters in field Where to select a Folderish document

'select2' widget for field Where only suggests Folderish documents from document default-domain
