This is sort of a side-post regarding a problem with strikethrough lines in kepubs on Formas. The original thread is:

The problem is that strikethrough lines (and possibly underlines now that I think about it), regardless of how they're produced, are so thin as to be almost invisible. I've tried various ways to tweak the CSS that should change the thickness of those lines, but they don't work. JSWolf confirmed that it was happening on kepubs and not epubs. He also wondered if a patch could be made. So, I popped over here (as a more suitable forum for that) to see if anyone knew if such a patch exists.
Let me include a screenshot of the problem:
and here's a wee epub I threw together to show that:
