In #3117291: Element::isEmpty() should check for #weight property a new way of checking whether a block is empty was introduced: before this, a block was considered empty if it only had a key of '#cache' set.
It was possible to return '#attached' and inject libraries etc into block content.
Ref https://github.com/drupal/drupal/commit/c3f6ce5cc04d7dc99ccc2eeebf72819d...
* Make a block plugin that returns '#attached' only
* block will not be rendered
I'll work on a patch. As a workaround set a '#dummy' key in your block plugin

miiimoooAttached a simple patch that just reverts the check for '#attached'
I haven't looked at the tests yet.

miiimoooThis patch also includes fixes for the "faulty" tests introduced by the commit

miiimoooUnless there is a good reason for the change this needs to go in to 10.0.x and 10.1.x too

larowlanYep this needs to go all the way back to 9.5 from 10.1

catchThis makes sense, wondering if we need a more generalised concept of not-content render array keys, but not for here. Committed/pushed to 10.1.x, cherry-picked to 10.0.x and 9.5.x, thanks!
