Create new not working as expected when using "foreign_selector" and "useCombination"
If the two options foreign_selector and useCombination are set, I get two buttons in my element in the backend - one "Create new" and one "Create new relation", whereby the second button is at the end of a select field.
If I click on "Create new relation" everything fits. A new relation is then created between the elements.
However, if I click on "Create new", a new data set is not created as expected but the data set that was presumably created last is used - i.e. a new relation is created.
The problem also already exists in 10.4.28 or earlier.
