Desc: Merge pull request #19100 from asutherland/email-html-word-wrap

Bug 1007560 - [Sora][Email] text/html messages do not have "word-wrap: break-word" in effect, so otherwise unbreakable lines of characters may trigger ridiculously zoomed-out newsletter mode. text/plain only has it applied for author-written text. r=jrburke
