Steps to reproduce :

• I have a content with a relation and an invert relation metadata.
• I open this content in edition mode.
• I create a new content from the metadata with the plus symbol and set the relation correctly.
• The new content is opened in a new window, the link is there to the first content.
• I come back to my first content.
• The form is not updated to set the relation then when I save it, the new relation is not set.
