Getting custom actions of a context menu to display on a content query web part

I have a situation where a SharePoint site has some custom actions on its document library context menu – both 3rd party and a simple bespoke action I have developed.

Now, the custom actions work fine when the context menu is displayed from a specific document library but do not get displayed on a content query which is rolling up doc lib items from multiple doc libs. To clarify, I have a context menu showing for this content query web part but it does not have the custom actions shown.

A lit search found the following question, which is basically identical to the issue, but remains unresolved. I have included the link to that query, in case it clarifies the issue:

Of course, I am using an (extended) content query webpart, but the question premise is the same…

So, long story, short, I am trying to leverage the greater skills of the broader SharePoint community to try to make this work. Thanks in advance.
