Perhaps such portions of text should only be cut-n-pasted as

This is a hard problem.  I don't have solutions, but I can say that
one very widespread non-free word processor sometimes does _HORRIBLE_

style to another portion of the document.  My suggestion would be to
stick to the KISS principle as much as it's feasible.
