MissingMandatoryParametersException: Some mandatory parameters are missing ("entity_queue") to generate a URL for route "entity.entity_subqueue.content_translation_delete

Here's a patch for this.

Committed and pushed to 8.x-1.x. Note that the subqueue's items are not translatable, see #3150981: Simple queue loses labels, cannot add new ones. Unusable on multi-lingual sites. → .

Thanks very much Andrei Mateescu. The issue is resolved now.
