I've updated from 4.08 to 4.09. I'm using the vertical align switch in the column settings, which worked in 4.08, but now doesn't in 4.09. However, it does work as expected when the page is in edit mode. When I use "inspect" in Chrome, vertical-align: middle; is showing as being active for the element, but something appears to be overriding it.
For example, on the page linked below, the sponsors have provided all different logo sizes, to me, having them all the same width, but vertically centred in their column is better visually. Vertical-align: middle is set in all cases in the column's settings. In the Event Partners section at the top of the page, I'm using padding to manually try and centre the logos relative to each other.
