CLEditor jQuery WYSIWYG v 0.5 + Vanilla 18.104.22.168 + IE 11 = "Body is required." error when posting.
Workaround for this seems to be clicking on Write Comment first, the typing the post, then Post Comment, but (a) kludge and (b) kind of sucks for the IE users, since it means they lose the formatting options, which is sort of the point of having the plugin.
I've tried the other editors that show up when I search for WYSIWIG plugins, but they all seem to be break in similar ways, though in different browsers or in different contexts.
Anyone sorted out a fix for this on their own, or know of a version of the editor that's newer than 2010 and doesn't have this problem?
