Warning: Invalid argument supplied for foreach() in Drupal\file_browser\Plugin\Block\ImageEmbedBlock->blockSubmit() (line 200 of modules/contrib/file_browser/src/Plugin/Block/ImageEmbedBlock.php).

Given this is 4 years old can I ask you to confirm this is still and issue on the 2.x branch of the module? If so please let me know so we can get this resolved once and for all. If the issue is resolved we can get this issue closed. Thank you.
