Thread:VisualEditor/Feedback/Ctrl Z doesn't work as expected/reply

Sorry about this; this should now be fixed here, and we'll get the code pushed wider tonight.

VisualEditor (actually, Parsoid) is intended to be used by users who have no idea about wikitext, as well as experts. Magically interpreting Foo as anything other than a nowiki block would fundamentally break the concept. If you don't write wikitext (or wikitext-like things) it won't get nowiki'ed. :-)
