This looks like a bug to me. My general intuition is that the syntax highlighting should use colors based on the category of tokens in the grammar: one color for all keywords, one color for all type names, etc.

That sounds right, I will try to see if I can fix it.

I am unable to understand the exact solution approach after exploring a bit. What i found was that PaymentRequest is getting captured as a support object either as "support.variable.dom.js" or as "support.class.dom.js" , in the concerto.tmLanguage.json file. (Image - https://imgur.com/a/MWIuYEp).
So, should PaymentRequest -

1. have the same color highlighting as PayOut and its other capturing group is overriden when used with a class definition before its declaration
2. remain as it is (not have the same color), but should throw error because it has already been captured and been declared as another type.
