Bug report #17805
QGIS forms cardinality configuration not correctly applied/saved

In the "Layer Properties" --> "Attributes Form" tab there is a list of relations (see screenshot attached).
When one clicks the relation of a n:m relation with an "in-between" table there is the possibility to hide the "in-between" table, because it only contains links to both other tables by setting the cardinality to "Tablename (primary key)".
This used to work before, but now the configuration is not correctly saved and no matter of the setting, the in-between table is always shown.
