Thanks for the report, and the test case object. I had a look at the IIIF spec and I feel like there's some ambiguity about whether a canvases annotations can target other canvases:
The motivation of the Annotations must not be painting, and the target of the Annotations must include this resource or part of it. https://iiif.io/api/presentation/3.0/#annotations
but later on, this seems reduced to a SHOULD
(perhaps allowing canvas annotations to target contained content resources?):
All of the Annotations in the Annotation Page should have the Canvas as their target https://iiif.io/api/presentation/3.0/#55-annotation-page

I think we also need some clarification about how to handle canvas annotations that target other canvases. Do we simply filter them out (because they are given in error, I guess?), or does mirador need to aggregate all the annotations in a IIIF presentation manifest (whether specified in the hierarchy for this canvas or elsewhere) to collect matching manifest, or some other behavior?
Can you share any real-world manifests with this behavior to help determine the appropriate user experience?
Hi.
I think it makes sense that if you are applying annotations to a particular canvas those annotations would have the same target. What I am not sure how to handle is when the annotation page is retrieved from an annotation server where the annotations belong to a container that is not specific to a canvas. It is at another level of abstraction. For example, a container of cats containing multiple annotations with different targets like this: https://miiify.rocks/annotations/cats This would require filtering on the target to avoid showing all annotations about cats on a single canvas. I wonder if there is another way to handle this in the manifest?
Hey all! Does this mean that when an annotation doesn't resolve, don't show it in the side menu?

Hi. When I view annotations and the annotation target does not match the canvas being displayed the annotation is still shown. Here is a simple example where the 2nd annotation is shown despite not having a matching canvas/target to display on: https://projectmirador.org/embed/?iiif-content=https://miiifystore.s3.eu-west-2.amazonaws.com/iiif/annotest.json
