Aspect ratio of full width box not calculated properly

[maadr]

I have an issue with full width boxes that pass the fullWidthBreakoutRowCadence condition. In my case I have all boxes with same aspect ratio (1.5), everything works fine until the container gets ~1080px wide, then when it gets wider full width boxes start to lose their aspect ratio and a content in them overlaps.

I guess I'm looking for option to set forceAspectRatio: true only to full width boxes, but afaik that's currently not possible, or am I missing something?

Here is the codepen with the issue reproduced: https://codepen.io/anon/pen/YdprBN
