On Extension:TimedMediaHandler the template doesn't display the "Added rights" section. This section is supposed to get populated automatically with the data from Module:ExtensionJson, but apparently it's failing here. And I don't know why.

It appears that, at one point in the distant past, Module:ExtensionJson contained:
["AvailableRights"] = {
[0] = "transcode-reset",
[1] = "transcode-status",
},
And it now says:
AvailableRights={
"transcode-reset","transcode-status",},
, which breaks my code that expects the old format. I've fixed it now.
