How To Remove or Reduce Gutters in Feature Info Widget Displaying Expression Content

[GregReinecke]

I have been putting expression generated content into an ExB Feature Info widget.  In AGOL they look fine as a popup but in the Feature Info widget they have a significant gutter.  A Text widget while different doesn't have a gutter at all when displaying text.  Any way to eliminate the gutter or have it be more reflective of text widget behavior?  Here is an example.  Thanks in advance.

Thanks for your feedback. It looks like a limitation user cannot modify the gap. 
Seems that you are using multiple Arcade expression in Popup? Would you be able to share a repro app for us to investigate further?
