Yes, it don't makes the rezise. Making the resize needs some extra logic cost that I considered not good idea to introducing. Only initial OpenKM version until 2.x version has it feature, but on major version I removed it, because cost of logic to re-calculate widgets size I consider was so much high that the benefits it produces. All widgets are calculated on pixels not % to get better rendering. Althought I can run some method to recalculate all object hierarchy, it suposes to introduce some extra logic on widgets that I considering it's not good idea to introduce. We can discuss on it ... I'm opened to listen you ...
