tmsfncricheditor paragraph color not supported?

I tried loading some RTF into a tmsfncricheditor that has paragraphs with a background color and it doesn't appear that it is supported (tested in a Win32 app). It is important for our needs, can this be added? I would need it supported for Android and iOS specifically.

tmsfncricheditor 1.8.10.1
Delphi 12.3

Can you share the RTF file so we can inspect what specific RTF tags were used here?
