Edit a Babel box that I'd just created.
Steps to Reproduce:
- Create a Babel box using the workaround described in bug 62740.
- Apply changes.
- Select the transclusion and click the puzzle icon to edit it again.
- It looks confusingly different.
If it can't add the function, then how is it able to edit it? And if it can edit it, then why can't it add it normally?
