Since Drupal Core 10.3.1 states on the form field entity_ids do not work any more.
...
'#states' => [
'visible' => [':input[name="settings[picture][browser][entity_ids]"]' => ['empty' => FALSE] ],
],
...
It is probably related to issue #3386191, as the 'once' function is now used there and therefore no more states are added to the field after the ajax request.
Does anyone have any ideas on how to solve the problem?
