LegendDecoration does not respect target size
Description
LegendDecoration is not working with the size param specification like this one
<decoration type="legend" affinity="top,left" offset="40,40" size="200,200"/>
It only works when i use
<decoration type="legend" affinity="top,left" offset="40,40" size="auto"/>
In the previous version 2.1.3 it works with that param
Environment
