Javascript, and default=hidden

@Purodha: Thanks for your report. I've fixed the issue in revision 7093059. It should now render as "expanded" by default when accessing without JavaScript. This is our default usually, but for some reason wasn't the case for "Template:Identical".

@Verdy_p: Purodha's expression "this template" is perfectly understandable given that this is a thread posted on the "Template talk:Identical" discussion board. Perhaps you were using Special:NewMessages to read this message and didn't notice the subject on the left side? (It's not the best interface, but it is what it is).
