Pasting doesn't format, normally.  As for highlighting...:
- If the structure is all on a single line, then the problem is likely
  just the usual (set of) "long lines" problem.
- If it's spread over many lines, then only a handful of lines (those
  that are visible) should be highlighted, so that shouldn't be it.

IOW, please M-x report-emacs-bug so we can try and figure out what went wrong,
