Model name containing comma leads to error

1. install Nuxeo
2. install nuxeo-template-rendering addon
3. start server
4. login to Nuxeo as Administrator
5. create a workspace testWks
6. inside testWks create a model named test,test and attach it a docx file (see attached simple-nuxeo-tr.odt)
7. create a Note document named myNote
8. bind the test,test template to myNote
9. head over to Associated Templates
10. click Render
11. observe everything works fine and the generated document is downloaded
12. now click the Summary tab
13. click the test,test link at the bottom-right part of the page in the Associated Templates zone. (scroll down if necessary). (see link.png)
14. observe an error is returned

Expected behavior: the generated file should be downloaded (as it is with the Render button)
Note: reproduced on 9.10 and master.
Pre-analysis: observing the generated url:

http://localhost:8080/nuxeo/nxtemplate/default/default-domain/workspaces/testWks/myNote@test,test?tabIds=%3A&conversationId=0NXMAIN2

the comma is not url encoded.
Using the following url does indeed download the generated document successfully:

http://localhost:8080/nuxeo/nxtemplate/default/default-domain/workspaces/testWks/myNote@test%2Ctest?tabIds=%3A&conversationId=0NXMAIN2
