window editing issue

[Wang]

Hello!

I use Grid with window editing mode,

and find a demo of window editing issue,

I opened the edit window many times,the height of the window will -1 every time.

you can click the edit link 6 times, the window content will show the scrollbar, window editing demo

how can I open the window without change the height every time?

thanks!
