Actual Behavior

After selecting a filter on a custom entity list, it initially works as expected. However, after reloading the page or navigating away and returning to the list, the previously selected filter value is no longer shown in the dropdown. This makes it possible to apply the same filter multiple times.

Expected Behavior

The select filter in custom entities should work like with articles - there the values are remembered.

Steps to Reproduce

Add a select to the list of your custom entity.

<property name="approval" visibility="always" searchability="yes" translation="app.review.approval">
    <field-name>approval</field-name>
    <entity-name>App\Entity\Review</entity-name>
    <transformer type="translation">
        <params>
            <param name="prefix" value="app.review.approval."/>
        </params>
    </transformer>
    <filter type="select">
        <params>
            <param name="options" type="collection">
                <param name="1" value="app.review.approval.1" />
                <param name="2" value="app.review.approval.2" />
                <param name="3" value="app.review.approval.3" />
            </param>
        </params>
    </filter>
</property>

Use the browser to test.

1. The select is empty initially

2. I clicked on some checkboxes

3. I applied the filter by clicking ok

4. I reloaded the page and take a peek at the selected options

5. I check some checkboxes

6. I see the label now contains the old and the new choices
