I've been creating a layout in ArcGIS Pro and have found what looks to be interesting behaviour. Does this seem logical or to be a bit of a bug?
When selecting elements and Distributing them vertically, I would expect this to be done using the element frame (extent). I've found though that in the case of a dynamic legend, it's using the top/bottom item within the legend as the reference point, and not the actual frame. Looking at my example below, where the limited features in the map frame results in the legend extent not being filled up by legend items, this results in items being distributed over the blank section of the legend. If I were to move my map and the legend were to grow (with more features being displayed in the map frame), this would then ruin the layout by overlapping the scale bar and text.
