Not a total unknown unknown, but this is the shortest example I've found so far of something that triggers an exponential slowdown in the input parser; this takes minutes to paste in an empty document. This kind of thing naturalistically occurs when a language model decides to return prose even though you specifically asked them not to.

Probably a wontfix pending new syntax model, but maybe a good regression test for the new setup.
