When downloading a graph from a dashboard widget (e.g. Graph, Scatter plot, or other widgets with a legend), the lower part of legend text is slightly cropped. Characters with descenders, such as "g", "y", "p", or "q", are partially cut off in the exported image.

Steps to reproduce:

1. Open a dashboard with a widget that includes a legend (e.g. Graph widget). 
2. Add items or datasets with names containing letters like "g" or "y" (e.g. "Available memory", "Connector queue").
3. Download image.
4. Check the legend text in the exported image.

Result: The lower parts of letters like "g", "y", "p", and "q" in the legend are cropped in the downloaded image.

 

Expected: Add several extra pixels of bottom padding in the legend rendering area during image export.
