When saving a mailing (mass_mailing) with invalid fields, the mailing
ended up having a height of 0. This is because some changes from
convert_inline are applied inline and may be incompatible with the grid
structure of the mailing. This was the case with height=0 applied on the
mail layout element as a result of it having a child with a height
expressed in percents. Rather than set the height to 0, we now set it
to whatever the height was measured to be.
