(Bug 60411): Fix TSR error for ";" list token in the tokenizer.

* For the normal parse scenario, looks like the list handler
  correctly sets up tsr on the new dt/dd/etc. tokens.

* Since the WTS escaping uses tokenizer tsr info directly, this
  only affects that code path.

* Updated existing nowiki escaping tests.
