Empty ad block is not hidden

Mind that there are two possible cases:
1. No matching ad generally exists for an ad block
2. The result of an existing ad is empty

I think we should not care for the second case.

There are two possible ways to solve this:
1. Checking if there is an ad for the block right before rendering the block at all (server-side)
2. Removing the block in JS if no ad is found for the block (client-side)

I'd tend to 1. because that also allows Drupal to hide the whole region that contains the block server-side

Might happen that we also need (2) later.

See our example boilerplate implementation.

lrwebks → changed the visibility of the branch 3399905-no-ad-bucket-handling to hidden.

Everything works as expected now!

@lrwebks please quickly add an update hook to set the new config value TRUE for existing installs. Afterwards let's merge this!

Update hook added.

I'll quickly resolve the MC.
