Page + Scrollbar + Autosize problems in Whiteboard

I have a really long page inserted into a Whiteboard.
You can cancel autosize and resize the page BLOCK. That page BLOCK will have a scrollbar for you to review the page.

So the problem is when I collapse the page Block and re-epand the block again, the AUTOSIZE is on again. I have to cancel it and do the resize all over again. This is rather painful for me.

How do I solve this and Is there a better way to do this?
