Yep, it was a trailing space
However, the < and > in the <br/> gets replaced by named enetities
The end result seems to be they're treated like normal text instead of a tag
So I'm wondering if it's even possible to title case multiple lines
BTW, I do it that way so that the TOC has both lines as an entry:
Chapter 1 Now It All Starts
Chapter 2 And It Keeps On Going
