Hi bshamblen,
I can not reproduce this issue.
My steps
1) Open Firefox 5.0 or Safari 5.0.5 for Windows.
3) In put { into editor textarea (normal view)
4) Click the Submit button (have tried the save button of the editor toolbar too)
Have you try on other pc? does it work for you?
by the way, I tried the old version of firefox/safari too, still works.
Regards,
Ken
