Configuration panel broken with complex configuration options

Looks like video transcoding/embedding might also have a problem?  I embedded an MP4....

Video transcoding works, but seems there may potentially be an incompatibility with this video. I'll look into that.

For the configuration issue, there should likely be a client-side error associated with the behavior you're seeing, either on first load of the panel or perhaps after a full page refresh. Can you share that? And can you also share the configuration definition?

The video was created with MS Snipping tool, I'll get the things shortly

Thanks. I wasn't able to replicate the transcoding issue in a dev environment, and attempting a re-encode here worked.

...

no console errors for other issuer, looks like the transcoder finally worked

Can you please share the configuration definition?

I have sent you a message with the code.
