I'm sorry.  The code for ZWNJ-as-space had a bug.  Please try the
attached new one.

Anyway, I also installed Nato Sans (i.e. NotoSans-Regular.ttf) by
"fonts-noto" debian package, but it seems that font does not support
Arabic.  If your "Noto Sans" font supports Arabic, please send me it.

With this method, if you are using the same "Noto Sans" font as mine,
you should see a visual glyph that "Noto Sans" defines for ZWNJ.
