Please fix the random font size bug that's been haunting the forums for some months now.

I guess the screenshots make it look like the first few words have become bigger, but in reality it's the latter part that's become much smaller. And with my eyes, it is really hard to read when the text suddenly becomes several font sizes smaller. And since it doesn't show in Compose or Preview, people don't even know there's a problem until they've already posted. Nor do they know how to fix it. And even if they do, the e-mail has already gone out.
Note: none of this was pasted in or anything like that. I did have a numbered list after "If you", though, before I changed my mind and removed it.
