I wanted to edit the lead section of an article just now, so I tried the standard trick of editing the first section and then changing &section=1 to &section=0. But then three weird things happened: 1. I got redirected to &section=0#892555963146827592. 2. I got a "Wikipedia does not have an article with this exact title" message and a blank edit box instead of the lead section I expected 3. I got a message from [[NoScript]] saying "NoScript filtered a potential cross-site-scripting attempt from [chrome:]." I know some sweeping preprocessor changes were rolled out recently -- would they have affected section 0 editing? (The specific article this happened on was [[Calliope (music)]], id=183157865.)
