Block Auto-size for iframe?

[victor.back]

Can you explain your use case? transform is applied to the parent plan container element so resetting transform of the iframe won't change anything.

I have set to auto-size in the visu settings.  But for a specific iframe thats open in one plan, I would like to not have auto-size, is this possible? 
Because the iframe is for a smaler size than the actual plan thats supose to be shown here, so I want to be able to scroll down inside the iframe. But when tha auto-size is on the view inside the iframe gets auto scaled and result in too small view.  

Hope I get the explanation good enough
