K2 is a much larger extension compared to RokPad. My guess is that K2 should be the reference point and not the other way around. We don't do anything fancy in terms of styling or HTML placement for our editor blocks. If it's not a JS conflict breaking the editor, then it should be relatively easy from RocketTheme to fix it. They have more resources than us either way...
