How is a symbol shape maintained without stretching to the patch size?
Attached images are legends in ArcMap and ArcGIS Pro to illustrate difference. In ArcGIS Pro, the symbol shape looks good in the layer in Contents, but in the Legend it is stretched to the patch size. Changing the patch size shifts the text of those legend items to the left, out of alignment with other text in the legend, because the patch is left-aligned. Shrinking all the patch sizes so the symbol shapes are not distorted reduces the line symbols, which makes dashing and doting in line symbols difficult to discern.
A workaround that requires turning the legend into graphics is unsuitable since it will not be dynamic.
I am using ArcGIS Pro 3.0
