Webform form elements are messed up when using this module.

Hello,

I have installed this module and it give nice feature to re-arrange form elements. This is really good module to use. Now i found one bug here. When i have used this interface panel for webform than on first part it worked perfectly but when i try to create webform form elements than it messed up. Instead of showing up all things in one line (as i have not used this for form elements) it shows at bottom of tables.

I found that there is no support for inner forms of webform. This bug is might be due to that. I have also attached screen image what i am getting.
