It seems that there is still an issue in the case of many templates aggregated together including at least one template redirect, which causes Uncaugth (in promise) missing in ve.dm.MWTransclusionModel.prototype.callTemplateDataApi and makes the edit page unusable. Try editing the infobox of https://fr.wikipedia.org/wiki/Elfie_(téléfilm) for example.
