I get {{Infobox example↵| parameter1 =↵| para2 =↵}} in both Chrome & FF, which is differently broken, we should be converting the newlines.

The issue here is that the pasted HTML is wrapped in a <pre> so it manages to bypass the line-splitting logic.

Is the "multiple spaces turn into non-breaking spaces" bit resolved? I thought that James reverted that part.

It should be. Reverted on 30 January, re-done on 2 Feb.
