Adding vedic accents in sanskrit in devanagari script in red color using Context - not working in all cases

Question

Using the techniques described in Coloring combining characters without changing color of a base character I have been able to color red the vedic accents in sanskrit typesetting using ConTexT MIV.

But, the coloring is NOT happening in all cases. For example it is not working in the very first word of the first line - हिर॑ण्यवर्णां॒ - but is working in the second word of fourth line - हिर॑ण्य .

How do I fix it?

(The font can be any unicode devanagari font that supports the vedic accents such as Siddhanta, Chandas, Sanskrit 2003 etc.)

\definefontfeature [vedic] 
            [devanagari-one]
            [goodies=vedic,       
            colorscheme=vedic,]       
\definecolor[colorscheme:1:1][r=1]  
\starttext
\definedfont[name:Siddhanta*vedic at 18pt]
\setupinterlinespace[line=2.8ex]
\setfontcolorscheme[1]
