To reproduce the issue
run the attached example IE9/10 or Chrome
- use the buttons to add/remove the "sclass"-attribute on the red columns
-> the height of the red columns is calculated incorrectly, if there is preceding sibling invisible by an sclass that uses "display: none", the inline style "display: none" does not cause this issue.
in FF23/IE8 the example looks as expected, all columns consume the remaining height of a div correctly, ignoring the invisible divs.
