Check and remove
Here the idea is to not trigger pictureViewsGenerationDone event while a concurrent work with the same id is running,
ensuring the event is sent only for the last work (
The id is: repositoryName + ':' + docId + ':' + xpath + ":pictureView",
so it is per blob which means that we are on the coalescing Work here, not a group of Work + trigger case.
This Work is not used anymore in master since
NXP-26420, should it be removed or annotate as deprecated?
