Currently, https://en.wikipedia.org/w/index.php?title=Help_talk%3ACitation_Style_1§ion=9&veaction=editsource is glitching for me. See https://en.wikipedia.org/w/index.php?title=Help_talk:Citation_Style_1&diff=prev&oldid=1248023743. (edit summary: Weird editor glitches introduced the wikitext edit I'm trying to fix with this edit. But as I'm making the fix, the editor is glitching again... The edit I made should have replace "I'mUser" with "[[User" but it looks like it won't. Very strange.) Somehow the editor acts as if the cursor isn't where I put it and see it, once I start typing. Something about the text in that section, perhaps. Reproducible by others?
