Ctrl-return split at wrong place after some HTML codes #16

If you have the following HTML in a Concord Example 1 app v0.5.3 headline:
I love Daytona ability to <a href="http://daytona.scripting.com/?q=drummer&collection=drummeruser">search all my drummeruser</a> files. Currently it finds 173 docs.

When you put your cursor at start of "Currently" and use ctrl-return to split the headline, it will break it at the wrong place 4 characters away at end of "Curr".

Further notes

1. If you put your cursor at start of "Daytona" that ctrl-return breaks it at the right place. That "Daytona" word is before the html code.
2. Merging the split two headlines with ctrl-backspace works in both cases.
3. I originally found this bug while editing in drummer v2.0.14.
