Maybe use a variable to hold getNumProperties()?

I think this comment is slightly misleading. It should be // Ignore this property if it is a shorthand.
but that's actually obvious from the code.

This logic is a bit hard to understand. I wonder if it would be easier to split the all and individual cases, to avoid having the strange step of breaking the loop after one iteration. It seems like you've made an effort to avoid duplicating code, but at the expense of being able to work out what's happening.

Anyway, I hope you can think of a more clear way to express what is happening here.

Sure, will fix in commit.

Will remove entirely, it is obvious.

Will try to improve the comment.
