That is clear and I agree, should be correct.
In the meantime I found the issue and maybe you can comment on that:
- form in dialog
- dialog + form settings are matching
- the form is a css layout with a tabpanel anchored left-right-bottom
- the tabpanel contains a form that is bigger than it should be.
This tab form causes the overflow on the main form.
Is this correct or should the tabpanel container show the scrollbars?
