Render With Template shows all template versions

When using the Template Rendering addon, a new user action is displayed to "Render With Template". This shows a list of available templates, but it includes all versions of each template document/object. I think this is defined in:

https://explorer.nuxeo.com/nuxeo/site/distribution/server-9.10/viewContribution/org.nuxeo.platform.TemplateSources.webui.operations--operation

where the search query is:

select * from Document where ecm:mixinType = "Template" AND ecm:currentLifeCycleState != "deleted" AND tmpl:applicableTypes IN ( "all", "' + input['type'] + '")'

I think this should include a clause to exclude document versions. e.g. ecm:isVersion = 0

Compare with the default query in the WebUI admin NXQL page:

SELECT * FROM Document WHERE ecm:mixinType != 'HiddenInNavigation' AND ecm:isProxy = 0 AND ecm:isCheckedInVersion = 0 AND ecm:currentLifeCycleState != 'deleted'

Should proxies be excluded too? i.e.

ecm:isProxy = 0

As it stands, it is very difficult to establish which entry in the list is the latest version of the template, and therefore will provide unpredictable results when rendering the output.
