I’m actually not sure how this could be caused since both of the cases where we use the dropdown button should _always_ have content.
Still, it’s safer to check for it when rendering so I committed this defensively:
[https://github.com/discourse/discourse/commit/e4e239c159bdf4973c3710d1fa16bf585d4d789c](https://github.com/discourse/discourse/commit/e4e239c159bdf4973c3710d1fa16bf585d4d789c)
I wouldn’t be surprised if there is a root cause out there still to track down but it should prevent errors.

Is there anything extra that needs to be logged / put in to help track down the possible extra root cause on this one?

Have not seen this in the logs in a long time, closing.
