Steps to reproduce the issue

Create a multingual site. 2 languages are enough.
Create a contact in each language and associate them in their edit page.
Load Multilingual Associations component.
Select Contact as type and one fo the languages.
Click on the greyed icon in the Associations column.
This will load the side by side page.

Expected result

When using the Associations Tab (or button in 4.0) for the reference and the target items, the field for the other language should display the name of the associated contact.

Actual result

It does not.
As you can see in the animated gif below, it does flash the name for a second at reload, then disapears as soon as the Target finishes loading.
